How many moles are in 12G hydrogen?
12 moles
What is the mass of 1 mole of carbon atom?
We use the equation: Mass = Number of moles * Molecular or atomic mass Since the number of moles is 1 ("one mole of carbon-12 atoms") and the atomic mass of carbon-12 atoms is 12, hence the mass would be 12 grams. Note that the unit grams (g) is used here, as it is the SI unit for mass measurement. I hope this is useful! :)
What is the mass carbon present in 44g of carbon dioxide?
Molecular weight of CO2 is about 44g (12g Carbon + 32g Oxygen *2 atoms Oxygen). So that means if you are presented with 44g CO2, that means there's 12g Carbon.
How many moles are in 48g of carbon?
To determine this we must first know what the molar mass of Carbon is and that equals 12.01g. This mean for every 12.01g of Carbon, we have one mole. Therefore:48gC x (1 mole C/ 12.01g C) = 3.99 molesRounded off, in 48g of Carbon there are about 4 moles.
What is the mass of 0.5 mol of carbon atoms in grams?
1 mole of carbon is 12.0107 grams Multiply by 5 and you get 60.0535 grams
How many moles are in 12G hydrogen?
12 moles
How many moles of atoms are in 4.1 x 10-12g O?
4.1 X 10^-12g O (1mol O/16g O )(6.022 X 10^23/1mol O )(1mol atoms O/6.022 X 10^23 ) = 2.56 X 10^-13 moles of atoms
How many moles are in 12g of potassium?
12 g of potassium is equivalent to 0,307 moles.
How many moles of NF3 are in 12g?
12 g NF3 equals 0,17 moles.

How many atoms are in 12g of carbon?
That is about the mole definition of Avogadro's number, so. 6.022 X 10^23 atoms of carbon
How many millimoles are in 12g of sodium hydroxide?
The molecular weight of sodium hydroxide is 40g/mol. To get the amount of moles, you have to divide the weight by molecular mass. 12g / 40 is 0.3 moles. This is 300 millimoles.
How many atoms in 3 moles helium?
For this you need the atomic (molecular) mass of H2. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel.3.00 moles H2 × 2.02 = 6.06 grams H2
What is the mass of 0.5 mol of carbon atoms in grams?
1 mole of carbon is 12.0107 grams Multiply by 5 and you get 60.0535 grams
What is the mass of carbon dioxide when carbon has a mass of 24 grams and oxygen has a mass of 32 grams?
Molecular weight of CO2 is about 44g (12g Carbon + 32g Oxygen *2 atoms Oxygen). So that means if you are presented with 44g CO2, that means there's 12g Carbon.
