What volume of 0.256 M sodium bromide contains 18.7 grams of bromide?
Need moles sodium bromide first. 18.7 grams NaBr (1 mole NaBr/102.89 grams) = 0.1817 moles NaBr =====================Now, Molarity = moles of solute/Liters of solution 0.256 M NaBr = 0.1817 moles NaBr/X Liters Liters = 0.1817/0.256 = 0.7098 Liters -------------------------( you do sigi figis )
How much potassium bromide in grams should be added to water to prepare 0.50L of solution with a molarity of 0.125M?
To calculate the amount of potassium bromide needed, use the formula: moles = molarity x volume (in liters). First, convert the volume to liters by dividing 0.50L by 1000. Then, multiply the molarity (0.125M) by the volume in liters to find the moles of potassium bromide needed. Finally, convert moles to grams using the molar mass of potassium bromide (KBr).
The mass of 3.45 liters?
The answer depents on the density of the substance involved. If the substance is water (density = 1) then 3.45 liters would have a mass of 3.45 kilograms. 1 kilogram = 2.2406 lbs so 3.45 kg = 7.61 lbs
How much is 84.9 liters in pounds in soil?
There is no direct conversion between liters and pounds of soil as they are measuring different properties (volume vs. weight). To convert liters to pounds, you would need to know the density of the soil. You would multiply the volume in liters by the density of the soil to get the weight in pounds.
How many liters of hydrogen gas are needed to react with CS2 to produce 2.5L of CH4 at STP?
The balanced equation for the reaction between hydrogen gas (H2) and carbon disulfide (CS2) to produce methane (CH4) is: 4H2 + CS2 → 4H2S + CH4. This means that for every 4 moles of hydrogen gas, 1 mole of methane is produced. Since 1 mole of any gas at STP occupies 22.4 liters, you would need 5.6 liters of hydrogen gas to produce 2.5 liters of methane.
1 liter of hydrogen is equal to how many kg?
To convert liters of hydrogen gas to kilograms, we need to know the density of hydrogen at a specific temperature and pressure. At standard conditions (0 degrees Celsius and 1 atmosphere pressure), the density of hydrogen gas is approximately 0.08988 kg/L. Therefore, 1 liter of hydrogen gas would weigh approximately 0.08988 kg.
What volume of 0.256 M sodium bromide contains 18.7 grams of bromide?

Pounds to liters?
Converting pounds to liters is not straightforward as they are units of weight and volume respectively, and the conversion depends on the density of the substance. To convert pounds to liters, you would need to know the density of the substance in question. Once you have the density, you can use the formula: volume (liters) = weight (pounds) / density.
How do you convert 0.770 grams to liters?
To convert grams to liters, you need to know the density of the substance. Once you have the density, you can use the formula: volume (in liters) = mass (in grams) / density (in g/mL). So, if you have the density of the substance, you can divide 0.770 grams by the density to get the volume in liters.
80 liters is how much kilo?
Liters are a measure of volume Kilos (Kilograms) are a measure of weight. So there are no liters (directly) in kilos. Weight and volume are related by Density: the more dense a substance the greater the weight of 80 liters. For example 80 liters of hydrogen weighs 7.2g which is much less than 80 liters of mercury which weighs 1082720g = 1082.72kg ~= 1.083 tonnes.
How many liters of hydrogen gas are in gaseous ammonia?
There are no liters of hydrogen gas in gaseous ammonia. Ammonia (NH3) consists of nitrogen and hydrogen atoms, but the hydrogen is chemically bonded to the nitrogen.
How much does 35 percent hydrogen peroxide weight per gallon?
Hydrogen peroxide has a density of about 1.2 grams per milliliter. To convert this to pounds per gallon, there are roughly 3.785 liters in a gallon (1 gallon = 3.785 liters) and 1 gram is about 0.00220462 pounds. Therefore, 35% hydrogen peroxide would weigh approximately 16.7 pounds per gallon.
How many liters of hydrogen gas are in a liter of liquid hydrogen?

How much potassium bromide in grams should be added to water to prepare 0.50L of solution with a molarity of 0.125M?
To calculate the amount of potassium bromide needed, use the formula: moles = molarity x volume (in liters). First, convert the volume to liters by dividing 0.50L by 1000. Then, multiply the molarity (0.125M) by the volume in liters to find the moles of potassium bromide needed. Finally, convert moles to grams using the molar mass of potassium bromide (KBr).
A kiloliter is equal to how many liters?
There is no definite answer to this question, as 23 litres of any two substances will have different density, and therefore different mass. 23 litres of water would not have the same mass as 23 litres of crude oil, which would not have the same mass as 23 litres of sand. In order to find the mass of your 23 litres of some substance, you would need to know the density of the substance. Once the density (in kg/l) of the substance, you can find the mass of the substance, since you know you have 23 litres of it, using this formula: Mass = Density*Volume For example, at room temperature, water (H2O) has a density of 1kg/l. If you wish to find out the mass of 23 litres of water, you would employ the formula in this manner: mass = (1)*(23) mass = 23kg Another example: Hydrogen peroxide (H2O2) has a density of 1.35 kg/l. The mass of 23 litres of Hydrogen peroxide would be found with: m = (1.35)*(23) m = 31.05kg
The hydrogen stored inside a large weather balloon weighs 13.558 g What is the volume of this balloon if the density of hydrogen is 0.089 gL?
Oh, dude, let me break it down for you. So, like, if the hydrogen in the balloon weighs 13.558 grams and the density of hydrogen is 0.089 g/L, then you can calculate the volume by dividing the weight by the density. That gives you a volume of 152.11 liters. So, like, that's how much space that hydrogen is taking up in that balloon. Cool, right?
How do you Convert tin density to liter?
To convert tin density to liters, you would need the volume of the tin as well. Once you have the density of tin (in units such as g/cm^3 or kg/m^3), you can use the formula: volume (in liters) = mass / density. This will give you the volume of tin in liters.
