Metric ton equals how many moles?
The number of moles in a metric ton depends on the substance being measured. To convert from metric tons to moles, you need to know the molar mass of the substance. You can use the formula: moles = (metric tons * 1000) / molar mass.
How do you convert 1.42 kg to moles?
You have to first convert Kilos to grams. 1.42 kilos is 1420 grams. Next you have to find out the molecular weight (can be added up from the periodic table). Now divide grams by molecular weight to get your final answer in moles.
What is the concentration of a solution expressed in moles of solute per 1000grams of solvent?
This concentration is known as molality, and it is expressed as moles of solute per kilogram of solvent. To convert from moles of solute per 1000 grams of solvent to molality, you need to convert the mass of the solvent from grams to kilograms before calculating the molality.
How many moles are in 29.4mg of BrI?
To find the number of moles, you first need to convert 29.4 mg of BrI to grams by dividing by 1000 to get 0.0294 g. Next, calculate the number of moles by dividing the mass in grams by the molar mass of BrI (which is 207.8 g/mol). Therefore, there are approximately 0.000141 moles of BrI in 29.4 mg.
How many moles C6H8O7 in 1000mg?
The atomic mass of the compound C6H8O7 is 6(12.0) + 8(1.0) + 7(16.0) = 192.01000mg is equivalent to 1g. Amount of C6H8O7 = mass of pure sample/molar mass = 1/192.0 = 0.00521mol There are 0.00521 moles of C6H8O7 in a 1000mg pure sample.
What would the mass of 1000 ml of aluminum?
To find the mass of 1000 ml of aluminum, you first need to know the density of aluminum, which is approximately 2.7 grams per cubic centimeter (g/cm³). Since 1000 ml is equivalent to 1000 cm³, you can calculate the mass by multiplying the volume by the density: 1000 cm³ × 2.7 g/cm³ = 2700 grams. Therefore, the mass of 1000 ml of aluminum is about 2700 grams.
What is the mass in grams of 25 mol of sodium hydroxide?
The molar mass of sodium hydroxide (NaOH) is approximately 40 grams/mol. To find the mass of 25 moles of NaOH, you would multiply the number of moles by the molar mass: 25 mol * 40 g/mol = 1000 grams. So, the mass of 25 moles of sodium hydroxide is 1000 grams.
How many moles of water are there in 1000 grams of water?
Water has a molecuar mass of 18. This means it weights 18g per a mole. The molecular formula for water is H20. Your answer for how many moles in 1000 grams of water is 55.5084351.
Convert 125 grams of calcium to moles?
For this you need the atomic mass of Ca. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.125 grams Ca / (40.1 grams) = 3.12 moles Ca
If 1000 g of PCP are dissolved in 1000 L of water what is the concentration in terms of moles per liter?
The molar mass of PCP (phencyclidine) is 243.387 grams per mole. So 1000 g of PCP is equal to 4.108 moles. If that many moles is in 1000 liters, than the molarity (in moles per liter) is 4.108 ÷ 1000 = 0.0041 M
How many moles of sodium are in 5.13 kg of sodium?
Quite a few! 5.13 kilograms sodium (1000 grams/1 kg)(1 mole Na/22.99 grams) = 223 moles of sodium =================
How do you convert 50 milli molar of sodium acetate into grams?
we know, 50 mM = 50/1000 moles per litre = 0.05 moles no. of moles = weight in grams/ weight of one mole weight of one mole of sodium acetate (CH3COONa) = 83g per mole no. of moles = 50/1000 = 0.05 moles thus weight in grams = 0.05*83 = 4.15 g
Metric ton equals how many moles?
The number of moles in a metric ton depends on the substance being measured. To convert from metric tons to moles, you need to know the molar mass of the substance. You can use the formula: moles = (metric tons * 1000) / molar mass.
How do you calculate milligrams of caffeine in 60 mL sample?
You have to know the concentration first. That will either be in grams per milliliter (or milligrams per milliliter), or it could be in moles per liter (molarity). If it's given in grams per milliliter, just multiply that number by 60 and multiply by 1000.If it's given in moles per liter, than first find how many moles in 60 mL by multiplying by 0.06, and then convert moles to grams using the molar mass of caffeine (194.19 grams per mole).See the Related Questions for how to convert moles to grams.
How many grams of koh are needed to prepare 250 milliliters of a 2 m solution of koh formula mass 56?
To prepare a 2 M solution of KOH, you would need to calculate the moles of KOH required first. Then use the formula mass of KOH (56 g/mol) to convert moles to grams. First, calculate the moles needed: 2 moles/L * 0.25 L = 0.5 moles. Then, convert moles to grams: 0.5 moles * 56 g/mole = 28 grams of KOH needed.
How do you calculate the number of moles in 4.637 grams in Mg?
For this you need the atomic mass of Mg. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.4.637 grams Mg / (24.3 grams) = .191 moles Mg
How do you convert 1.42 kg to moles?
