How many moles are there in 5gram of sulphur?
Atomic mass of Sulphur is 32 1 mole = Atomic mass of sulphur No. of moles = Given mass/ Atomic mass No.of moles= 5/32 0.15 moles
What mass of water is 2.000 mol of water?
The mass of 2 moles of water is 36 g.
How many moles of water are on 72.08g of H2O?
The molecular formula of water is H2O. The atomic mass of H2O is 2(1.0) + 16.0 = 18.0Amount of H2O = mass of pure sample/molar mass = 75/18.0 = 4.17mol There are 4.17 moles of water in a 75 gram pure sample.
How many moles are in 1.2 mg of oxygen?
The molar mass of oxygen is 32 g.1,2 mg oxygen is equal to 0,0000375 moles.
How do you convert grams to moles using avogadros number?
You don't need to use Avogadro's number, you need the mass of the molecule in atomic units. Mass / molecular mass = moles eg for water, 36 grams / 18 atomic units = 2 moles
How many moles are there in 5gram of sulphur?
Atomic mass of Sulphur is 32 1 mole = Atomic mass of sulphur No. of moles = Given mass/ Atomic mass No.of moles= 5/32 0.15 moles
What is the mass of 0.5 moles of water?
The mass of 0,5 moles of water is 9 g.
How many moles of oxygen are represent in 0.16 g of oxygen gas?
using the equation moles=mass/molar mass (since its in gas form) O2 => 16*2 =32 0.16/32=0.005 moles :)
How many moles are there in 5 grams of silicon dioxide?
number of moles=mass/molar mass =5/(28+32) =0.83 mol
How would you find out how much 12.4 moles of water weigh?
Multiply moles by molecular mass of water (18), gives you 223.8g. Remember this formula: Number of moles = mass / molecular mass
How many grame are in 2.4 moles of sulfur?
one mole of sulfur has a mass of 32 g --- its atomic mass. so just multiply by 2,4 moles
What mass of water is 2.000 mol of water?
The mass of 2 moles of water is 36 g.
What mass of water will contain 2.80 moles of water?
number of moles = Massdivided by Molar Mass 2.80 = Mass divided by 18.012.80 X 18.01 = MassMass = 50.43 grams.
How many moles of water are on 72.08g of H2O?
The molecular formula of water is H2O. The atomic mass of H2O is 2(1.0) + 16.0 = 18.0Amount of H2O = mass of pure sample/molar mass = 75/18.0 = 4.17mol There are 4.17 moles of water in a 75 gram pure sample.
What is the mass of 32 of water?
