What is the mass of a powder if the combined mass of the powder and it's container is 12 grams and the mass of the mass of the mass of the container aloNe is 4 grams?
it is 8 because all you have to do is subtract 4 out of 12 and what does that give you...8 pretty simple stuff <3
Convert grams to moles?
To convert grams to moles, you need to know the molar mass of the substance. Divide the given mass in grams by the molar mass to find the number of moles. This calculation is done using the formula: moles = grams / molar mass.
If the density of seawater is 1 and four hundredths grams per centimeter cubed what is the mass of 1000 centimeter cubed of sea water?
The mass of 1000 cm^3 of seawater can be calculated by multiplying its density (1.04 g/cm^3) with the volume (1000 cm^3). Mass = Density x Volume Mass = 1.04 g/cm^3 x 1000 cm^3 Mass = 1040 grams Therefore, the mass of 1000 cm^3 of seawater is 1040 grams.
A solid object has a mass of 30 grams and a volume of 10 cm cubedwhich is the density of the object?
The density of the object can be calculated using the formula: Density = Mass/Volume. Plugging in the values, Density = 30 grams / 10 cm^3 = 3 grams/cm^3. Therefore, the density of the object is 3 grams/cm^3.
If the mass of the container is 14.5 grams what is the mass of the sand?
To determine the mass of the sand, you'll need to subtract the mass of the container (14.5 grams) from the total mass of the container with sand in it. For example, if the total mass of the container with sand is 50 grams, then the mass of the sand would be 50 grams - 14.5 grams = 35.5 grams.
If formula for ammonia is NH what is the mass of 3 moles of ammonia would be in grams?
The molar mass of ammonia is about 17 grams, so that 3 moles would have a mass of 51 grams.
What is the mass of an object that has a mass of 24 grams and a volume of 3 ml?
The mass of the object is already given as 24 grams. The volume of 3 ml is not necessary for determining its mass, but it can be used to calculate the density, which would be 8 grams per milliliter (24 grams / 3 ml). Therefore, the mass remains 24 grams regardless of the volume.
Mass of 3 moles of ammonia would be?
The molar mass of ammonia is about 17 grams, so that 3 moles would have a mass of 51 grams.
The formula for ammonia is NH3 the mass of 3 moles of ammonia would be how many grams?
The molar mass of ammonia is about 17 grams, so that 3 moles would have a mass of 51 grams.
What is the mass of 3moles of oxygen?
The molar mass of oxygen is approximately 16 grams/mol. Therefore, the mass of 3 moles of oxygen would be 3 moles * 16 grams/mole = 48 grams.
Mass of 3 moles of ammonia?
Molar mass of ammonia = (14.01 + 3.03) (Molar mass of nitrogen + 3 times molar mass of hydrogen, as chemical formula of ammonia is NH3). Molar mass= 17.04 Molar mass x moles = mass 17.04 x 3 = 51.12 Mass of 3 moles of ammonia is 51.12g.
The mass of 3 moles of ammonia would be how many grams?
3 moles of ammonia is 51grams. One mole is 17 grams.
How much is the mass of a pencil which is 3 grams of weight and 20 cm long?
3 grams.
What is the density of a - solid object has a mass of 30 grams and a volume of 10 cm3?
The density of the object is 3 grams per cm3. This is calculated by dividing the mass (30 grams) by the volume (10 cm3).
What is the mass of a caterpillar?
The mass of a caterpillar depends on the species. On average, a caterpillar will weigh between 0.2 and 0.5 grams.
How many grams are there in 3 moles of CuSO4?
The molar mass of CuSO4 is 159.6 g/mol. To find the mass of 3 moles of CuSO4, multiply the molar mass by the number of moles: 3 moles * 159.6 g/mol = 478.8 grams. Therefore, there are 478.8 grams in 3 moles of CuSO4.
The formula for ammonia is NH3. The mass of 3 moles of ammonia would be grams.?
The molar mass of NH3 is 17.03 g/mol. To find the mass of 3 moles of NH3, you would multiply the molar mass by 3. Therefore, the mass of 3 moles of ammonia would be 51.09 grams.
