How many moles are in 16g NaCI?
To find the number of moles in 16g of NaCl, we first need to calculate the molar mass of NaCl, which is approximately 58.44 g/mol. Then, we can use the formula: moles = mass / molar mass moles = 16g / 58.44 g/mol moles ≈ 0.27 mol
How many moles 64 grams of ch4?
First, determine molar mass of CH4: C:12g/mol + 4x H:1g/mol= 16g/mol Then divide by the number of grams. 64g/(16g/mol)= 4 moles of CH4
How many number of moles of carbon dioxide that are contain 16g of oxygen?
To calculate the moles of carbon dioxide, we first need to determine the number of moles of oxygen in 16g. Using oxygen's molar mass of 16 g/mol, we find that there is 1 mole of oxygen in 16g. Since one mole of oxygen reacts with one mole of carbon dioxide in the balanced equation, there will also be 1 mole of carbon dioxide formed.
How many moles of atoms are there in 3.968x1023 atoms Mg?
Divide that number by Avogadro's number: 3.968x10(23) / 6.02x10(23) = 0.659mol Mg, which would be about 16g.
How many atoms are in 16g O and 8g S?
To find the number of atoms in 16g of oxygen (O) and 8g of sulfur (S), we first calculate the number of moles for each element. Oxygen has a molar mass of about 16 g/mol, so 16g of O corresponds to 1 mole (6.02 x 10²³ atoms). Sulfur has a molar mass of about 32 g/mol, so 8g of S corresponds to 0.25 moles (1.51 x 10²³ atoms). Therefore, the total number of atoms is 1.76 x 10²³ (1 mole of O + 0.25 moles of S).
How many moles in 64 grams of CH4?
There are 0.75 moles in it.You have to devide 12 by molecular mass
How many moles of He are in 16 g of element?
using the formula: n=m/gfm no. of moles=mass/gfm you take the gram formula mass (gfm) as 4. and given the mass is 16g, both numbers can be substituted into the formula... n=16/4 = 4 the number of moles present in 16g of helium is 4 moles.
What is 12g of carbon with 32g of oxygen?
To calculate the moles of each element, you need to divide each mass by the molar mass. The molar mass of carbon is 12g/mol and oxygen is 16g/mol. 12g of carbon divided by 12g/mol gives 1 mole of carbon. 32g of oxygen divided by 16g/mol gives 2 moles of oxygen.
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 moles are present in 4g sodium hydroxide?
To determine the number of moles in 4g of sodium hydroxide (NaOH), divide the mass by the molar mass of NaOH. The molar mass of NaOH is approximately 40g/mol (Na = 23g/mol, O = 16g/mol, H = 1g/mol). Therefore, 4g of NaOH is equal to 0.1 moles.
