How many atoms are in sample of chromium with a mass of 13 grams?
Take the actual sample weight of 13grams, and divide it by the atomic weight of chromium. This gives you your molar percentage of atoms. Now multiply this molar percentage by Avogadro's constant, the number of atoms in one mole, and this will give you your number of atoms in the sample.
What is the molar mass of casein?
Milk is not a uniform compound, and it is a mixture. Therefore the content of milk may differ from one sample to another. Hence, a molar mass for milk cannot be defined.
How many moles 0.170g C?
The atomic mass of carbon, C is 12.0Amount of C = mass of sample/molar mass = 0.170/12.0 = 0.0142mol There are 0.0142 moles of carbon in a 0.170g pure sample.
What is the mass of a 1 mole sample of neon gas?
Chlorine is non metal element. Atomic mass of it is 35.
A sample of cinnamaldehyde C9H8O contains 0.0976 mol of the compound What is the mass off the sample in grams?
Multiply the number of moles (0.0976) by the molar mass of C9H8O (9*12.0+8*1.008+16.0= 132.1) in units: moles * grams/mole = grams
How prepare 6N ammonium hydroxide?
6N ammonium hydroxide (NH4OH) is the same as 6 M NH4OH. The molar mass of NH4OH is 35 g/mole. Dissolve 6 x 35 g = 210 g NH4OH in enough H2O to make 1 liter of solution.
How many moles are in acetylsalicylic acid?
The molar mass of acetylsalicylic acid is 180.157 g/mol. There is a calculation involved in order to find the number of moles in a sample of ASA in which you divide the mass of your sample with the molar mass.
How many atoms are in sample of chromium with a mass of 13 grams?
Take the actual sample weight of 13grams, and divide it by the atomic weight of chromium. This gives you your molar percentage of atoms. Now multiply this molar percentage by Avogadro's constant, the number of atoms in one mole, and this will give you your number of atoms in the sample.
How to prepare ammonium hydroxide solution?
You will mix NH4OH with water. To get a specific concentration you will need to calculate the number of moles required and covert this to a mass. Use the molar mass of NH4OH. eg. 100 mL of 0.5 mol/L NH4OH -> 35.06 g/mol x 0.5 mol/L x0.100 L Notice the units cancel to g. Obtain this amount using a balance and add water to 100mL.
How many moles contained in 14.2g of barium sulfate?
The molar mass of barium sulfate, BaSO4 is 233.4 Amount of BaSO4 = mass of sample / molar mass = 14.2/233.4 = 0.0608mol 0.0608 moles of BaSO4 are conained in a 14.2g pure sample.
A sample of a compound contain 1.52 g of Nitrogen and 3.47 g of Oxygen. The molar mass of this compound is between 90 grams and 95 grams. Determine molecular formula and the accurate molar mass.?
A sample of a compound contain 1.52 g of Nitrogen and 3.47 g of Oxygen. The molar mass of this compound is between 90 grams and 95 grams. The molecular formula and the accurate molar mass would be N14O35.
How can you get the molar mass of insulin knowing just the grams of insulin in a sample and the number of molecules that that sample contains?
by weighing out the bit of insulin that you want to find how much of it there is
What the molar mass of NH3?
36.084g/mol is INcorrect1*14.01 + 4*1.008 = 18.042 g/mol for NH4, but this is not an exsiting compound.Ammonia is NH3 (17.034), ammonium is NH4+(18.042).
How do you find moles of a chemical with density and molar mass?
You need also to know the volume or the mass of the sample.
How many moles are in 317.0 g of BaOH2?
Molar mass of barium hydroxide, Ba(OH)2 = 171.3Amount of barium hydroxide = mass of sample / molar mass = 317.0/171.3 = 1.85mol
When finding the moles of a gram sample of a diatomic element do you divide by twice the molar mass?
YE you do divide by 2
