How many oxygen molecules are there in in 4 g of oxygen?
Assuming you mean oxygen gas, the number of molecules can be found by first finding the number of moles = mass of oxygen (4g) / Molecular mass of oxygen gas (32 g mol-1) This tells us there is 0.125 mol of oxygen gas present. The number of molecules present is given by the number of moles x the avogadro constant (6.022x10^23) So the number of oxygen gas molecules present is equal to 0.125 x 6.022x10^23 = 7.5275x10^22 molecules
What mass of oxygen contain the same number of molecule as 42g of nitrogen?
Both nitrogen and oxygen exist at standard temperature and pressure as diatomic molecules. Therefore, the relative masses of equal numbers of molecules of the substance will the same as the ratios of their atomic masses, which are 15.9994 for oxygen and 14.0067 for nitrogen. The mass of oxygen that contains the same number of molecules as 42 g of nitrogen is 42(15.9994/14.0067) or 48 g, to the justified number of significant digits.
How many molecules are there in 65 g of silver nitrate?
Well, because you have 65g of AgNO3, you have .3826 moles of silver nitrate. This is found by dividing the number of grams you have by the molar mass of silver nitrate (169.9g/mol). Once you know how many moles there are you can then multiply by Avogodro's number (6.022x1023) to obtain the number of molecules. In this case it is 2.304x1023 molecules.

If you have 4.5 X 10 24 atoms of CH4 how many grams do you have Please help and explain how you got the answer?
The molar mass of methane is 16,04 g.1 mol has 6,022 140 857.10e23 molecules. In your question the correct word is molecules not atoms.6,022 140 857.10e23---------------------------------16,04 g4,5.10e24---------------------------------------------------xx = (4,5.10e24 . 16,04)/6,022 140 857.10e23 = 119,6 g
How many molecules of H2(g) are there in a 21.25 gram sample?
The number of molecules is 6,3985.10e24.
Which has more molecules 16g of CO or 20g of N2?
There are 6.023x10^23 molecules in one mole of a compound. So now, you have to find how many moles of each compound you have. CO's molecular weight is (12+16) = 28 g/mol N2's molecular weight is (14+14) = 28 g/mol So you find the moles of each. moles of N2 = 20g/ 28g/mol = .714 moles moles of CO = 16g / 28 g/mol = .571 moles So, N2 has (.714 *6.023x10^23) has 4.3 x10^23 molecules and CO (.571 *6.023x10^23) has 3.4x10^23 molecules. So, 20g of N2 has more molecules than 16g of CO

How many molecules of water are there in 12g of ice?
[10.0(g) / 18.0(g/mol H2O)] * 6.02.10+23(molecules/mol) = 3.34.10+23 molecules in 10 g of H2O(never mind the physical state: solid, liquid, vapor; it's all 10.0 grams of it)
What does the Avogadro number represent?
Avogadro's number is the relation to 1 u with 1 gram in mol so if an atom weighs 12 u (C-12) 1 mol weighs 12 grams and 12 mol is 6.0221415 × 1023 u
How many molecules are in 12.5g of water?
The molar mass of water (H2O) is approximately 18 g/mol. To calculate the number of molecules in 12.5 g of water, we need to convert grams to moles by dividing by the molar mass. 12.5 g / 18 g/mol = 0.694 moles. Since 1 mole of any substance contains 6.022 x 10^23 molecules (Avogadro's number), multiplying 0.694 moles by Avogadro's number gives us approximately 4.18 x 10^23 molecules of water in 12.5 g.
