The mass of a mole of zinc is approximately?
The molar mass of zinc is 65,38 g.
What is the mass percent of a solution that is prepared by dissolving 4.0 g of KCl in 50.0 g of H2O?
Mass percent is the ratio of the mass of solute to the total mass of solution expressed as a percent Here we have 4.0 g solute and total mass of solution of 4.0 g + 50.0 g = 54.0 g. So, the mass percent of KCl = 4.0 g/54.0g (x100) = 7.41% (3 sig figs)
How is a number of moles of an element determined from a known mass?
The number of moles is mass in g/molar mass in g.
What is the mass of 2.6 g of magnesium and 1.6 g of oxygen?
The molar mass of magnesium is 24.31 g/mol, while the molar mass of oxygen is 16 g/mol. To find the mass of 2.6 g of magnesium, you can divide 2.6 g by the molar mass of magnesium (24.31 g/mol) and multiply by Avogadro's number to find the number of moles. Similarly, you can do the same calculation for 1.6 g of oxygen and then sum up the molar masses to find the total mass.
What is the percentage of mercury (by mass) in the 4.75 g of dimethylmercury?
Dimethylmercury = (CH3)2Hg and molar mass = 230.7 g/moleatomic mass Hg = 200.6Percent Hg by mass = 200.6/230.7 (x100) = 87.0 %.This is the percent in 4.75 g or 47.5 g or in 475 g. It won't change. If you need the mass of mercury in 4.75 g of diemthyl mercury, then it will be 4.75 g x 0.87 = 4.13 g4.13 g/4.75 g (x100) = 87% Hg
What is the least number that should be subtracted from 18448 to make it exactly divisible by 48?
It is: 16 because 18448-16 = 18432 and 18432/48 = 384

An empty beaker has a mass of 115 g After some water is added to the beaker the mass is 147 g What is the mass of the water?
32 g
What is the mass of oxygen in 5.2 g of potassium nitrate?
This mass is 2,469 g.
What would be the percent concentration of 54.0g of AgNO3 is dissolved in 128g of water?
mass (g) solute divided by total mass (g)times 100%total mass (g) = [mass solute + mass (g) solvent]54.0 / [128 + 54.0] = 29.6%
What is the mass of 17 moles of titanium?
Mass(g)= moles x molar mass 17 x 47.87 =813.79 g Mass(kg)= 813.79 g/1000 =0.81379
