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
10 times as much as in 1 mole. In other words, you just need to look up the molar mass of sodium, then multiply that by 10.
229.9 grams.
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.
The molar mass of boron is approximately 10.81 grams per mole.
If 3,6 x 10-5 is grams the number of atoms is 1,1.10e17.
The molar mass of iodine (I) is approximately 127 grams/mol. So, for 10 moles of iodine atoms, the mass would be 10 moles * 127 grams/mol = 1270 grams.
The molar mass of ammonia (NH3) is 17 g/mol. Therefore, the mass of 10 moles of ammonia would be 170 grams (10 moles x 17 g/mol).
180 grams of water is 10 moles of water.
320 grams of oxygen is the equivalent of 10 moles.
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.
The molar mass of boron is approximately 10.81 grams per mole.
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 in 180 grams of water, divide the mass by the molar mass of water. The molar mass of water is approximately 18 g/mol (2*1 (hydrogen) + 16 (oxygen)). So, 180g รท 18 g/mol = 10 moles of water.
To find the number of moles in 10.0 g of nitrogen dioxide (NO2), you first need to find the molar mass of NO2, which is approximately 46.01 g/mol. Then, divide the given mass by the molar mass to get the number of moles. In this case, 10.0 g / 46.01 g/mol โ 0.22 moles of nitrogen dioxide.
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
If 3,6 x 10-5 is grams the number of atoms is 1,1.10e17.
6.066 into 10(up 23 )
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)
