The atomic mass of Al is 27.0 Amount of Al in a 50g pure sample = 50/27.0 = 1.85mol
To determine the number of moles of N2 in 50g, you first need to find the molar mass of N2 (28.02 g/mol). Then, you divide the given mass (50g) by the molar mass to get the number of moles. In this case, 50g / 28.02 g/mol ≈ 1.79 moles of N2.
To determine the number of moles in 50g of NaCl, you first need to find the molar mass of NaCl, which is approximately 58.44 g/mol. Then, you divide the given mass by the molar mass to find the number of moles. So, 50g of NaCl represents approximately 0.855 moles (50g / 58.44 g/mol = 0.855 mol).
To determine the number of moles in a 50g sample of estrogen, you need to know its molecular weight. The molecular weight of estrogen (specifically estradiol, a common form) is approximately 272.38 g/mol. Using the formula: moles = mass (g) / molar mass (g/mol), you can calculate the moles: 50g / 272.38 g/mol ≈ 0.183 moles of estrogen in the sample.
The reaction is:2 Ag2O-------------4 Ag + O2The answer is o,43 mole silver.
A 50g sample of H2O contains approximately 2.78 x 10^24 molecules of water. This is calculated by first converting the mass to moles, then using Avogadro's number to determine the number of molecules present in that many moles of water.
This is a mass stoichiometry problem. Start with the balanced equation: CaCO3 --> CaO + CO2. Do a conversion from 50g CaO to moles: 56g/1mol=50g/x, x=.9 moles. The equation is balanced as written, with all coefficients understood to be 1. So: .9 moles CaO means .9 moles CaCO3. Do another conversion from moles to grams: 100g/1mol=x/.9 moles. Solve for x to get 90 grams. (56g=molar mass of calcium oxide; 100g=molar mass of calcium carbonate.)
In the equation N2+3H2=2NH3, the amount of ammonia produced from 50g of N would be 16.667g.
50g of what ?
There are 20 50g in 1kg. This can be calculated by dividing 1000g (1kg) by 50g to get the result.
5 of them make 50g
Yards are a linear measurement. 50g (meaning grams) is a weight. So there can't be any yards in 50g.
