The mass of 1 mole of a substance is the atomic weight of that substance.
Na has an atomic weight of approx 22.99 g/mole
→ 10 moles weight 10 moles × 22.99 g/mole = 229.9 g
To find the number of moles, you need to divide the given mass (10 grams) by the molar mass of HCl (36.46 g/mol). This will give you approximately 0.274 moles of HCl.
1.00*10-7 moles of boron is how many grams is this
If 3,6 x 10-5 is grams the number of atoms is 1,1.10e17.
Iodine has a molar mass of 129.9g So one mol of Iodine is 129.9g. Therefore 10 moles of iodine would be 1299g.
If ammonia (NH3) has a molar weight of 17 grams per mole, then 10 moles means 17x10=170 grams.
320 grams of oxygen is the equivalent of 10 moles.
180 grams of water is 10 moles of water.
10 grams aluminum (1 mole Al/26.98 grams) = 0.37 moles of aluminum ---------------------------------
10 moles of sodium chloride have 584,397 g.
To find the number of moles, you need to divide the given mass (10 grams) by the molar mass of HCl (36.46 g/mol). This will give you approximately 0.274 moles of HCl.
6.066 into 10(up 23 )
2.3 grams P (1mole P/30.97 grams) = 0.07427 moles Phosphorous 0.07427 moles P * 6.022 X 10^23 = 4.5 X 10^22 atoms of P in 2.3 grams P 4.5 X 10^22/6.022 X10^23 = 0.07427 moles of atoms in 2.3 grams of phosphorous
Let's see. 3 moles gold (197.0 grams/1 mole Au) = 591 grams of gold ----------------------------- 10 mole iron (55.85 grams/1 mole Fe) = 558.5 grams of iron ----------------------------- So, 3 moles of gold has more mass that 10 moles of iron. (heavier)
1 mole Na = 22.989770g 10 moles Na = 10 x 22.989770g = 229.89770g
1.00*10-7 moles of boron is how many grams is this
If 3,6 x 10-5 is grams the number of atoms is 1,1.10e17.
Iodine has a molar mass of 129.9g So one mol of Iodine is 129.9g. Therefore 10 moles of iodine would be 1299g.
