How many grams of lead nitrate will dissolve in 100mL of cold water?
56g
What is the percent composition of calcium (Ca) in (CaO)?
40 g / 56 g X 100%
How many grams of calcium carbonate are required to prepare 50.0 g of calcium oxide?
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.)
How many moles of iron atoms are there in 56g of iron?
The amount of particles (any kind) in ONE mole (of any substance) is always equal to Avogadro's number: 6.02*10+23 (This is the definition of a 'Mole'. It is just a number like a 'dozen' -12- or 'gross' -144-, though much larger. There is nothing 'chemical' in this number, however) So, here is your answer: 0.56 mole = 0.56 * 6.02*10+23 = 3.37*10+23
What does 56g equals?
56g=0.56kg
What is the density of an object with a mass of 56g and 90 ml?
Density = Mass/Volume = 0.622... grams per ml
What is the density of a ball that has a mass of 56 g and a volume of 28 cm?
Assuming the volume is in cubic cm and not cm(!), Density = Mass/Volume = 56g/28cm3 = 2 grams per cm3
What is 130 percent of 56g?
130% of 56g = 130% * 56 = 1.3 * 56 = 72.8g
What is the volume of an object with a mass of 25 point 8g and also has a density of 2 point 56g?
Density = Mass/Volume => V = M/D So Vol = 25.8/2.56 = 10.1 units (approx) of the volume in which the density was expressed.
What is the significant figures for 56g?
2 significant figures.
Calculate the number of moles in 112 g of iron?
Molar mass of iron is 56g. Given mass of iron= 112g No. of moles = Given mass/Molar Mass => 112g/56g= 2 moles
