How many moles are in 42 grams of CO2?
just short of a mole. moles is mass/molar mass. mass is 42, molar mass is 44. 42/44
Which mathematical relationship should you use to convert moles of a substance into grams?
Multiplication by what is called a conversion factor. A moles x (bbb grams / 1 mole) in which bbb is the molar mass of the substance.
How many grams are in 1.11 moles of manganese sulfate Mn3SO47?
molec weight is 151g/mol. 1.11 moles x 151g/mol is 167.61g Moles is mass / molecular mass
How do you convert 5.2 moles of lead to grams?
Using the formula number of moles = mass divided by molar massso mass = number of moles X molar massFind molar mass by adding up the masses of all the atoms in your substance.A good way to remember this is as the formula g/mw = moles, and the mnemonic for this is"Mine workers (mw= molecular weight) under ground (grams of compound you are dealingwith = Moles!
Millimoles to grams?
number of moles present = molar mass (g) 1 mol The molar mass is the sum of the atomic masses present in a compound. Be sure to take quantity into acount. For intance... the molar mass of H2O is 18.02 because 1.01+1.01+16=18.02
How many moles are in gram of NaOH?
moles = mass/Mr moles = 100/(23+16+1) moles of NaOH = 2.5mol
20 grams of NaOH to moles?
mass divided by molar mass gives moles: 20 g NaOH / 40 g.mol-1 = 0.5 mol NaOH
How many moles are there in 9.4 g of NaOH?
Molecular mass of NaOH= 40.0 grams9.40 grams / (40.0 grams) = .235 moles NaOH
How many grams does 2.2 moles of NaOH weigh?
Need total molar mass sodium hydroxide which you can easily get from your periodic table. 2.2 moles NaOH (39.998 grams/1 mole NaOH) = 88 grams in mass ==============
What is 83 grams of sodium hydroxide in moles?
For this you need the atomic (molecular) mass of NaOH. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. NaOH= 40.083.0 grams NaOH / (40.0 grams)= 2.08 moles NaOH
What is the mass of 2.75 moles of sodium hydroxide?
Molar mass of NaOH is 39.998 grams. So, 2.75 mol NaOH (39.998g NaOH/1 mol NaOH) = 109.9945 grams NaOH ( you do the sigi figi )
How many liters of naoh are in 1.3 moles of 3.42 m of naoh?
Molarity = moles of solute/Liters of solution 3.42 M NaOH = 1.3 moles NaOH/Liters NaOH Liters NaOH = 1.3 moles NaOH/3.42 M NaOH = 0.38 Liters
How do you find moles of acidic h atoms?
.1146g of mass of Unknown and 12.00ml of NaOH. Find the moles of acidic H atoms
How many moles of NaOH are in 8 g of NaOH?
8 grams NaOH (1 mole NaOH/39.998 grams) = 0.2 moles NaOH
How many grams of of NaOH are required to prepare 200 mL of a 0.450 M solution?
Molarity = moles of solute/volume of solution 0.450 M = m/200ml = 90 millimoles, or, what we need; 0.09 moles 0.09 moles NaOH (39.998 grams NaOH/1 mole NaOH) = 3.60 grams of NaOH needed
How many moles in 30.0 g of NaOH?
0.75 moles in 30.0g of NaOH.
How many moles are in 15 mL of 2.9 M NaOH?
Molarity = moles of solute/liters of solution ( 15ml = 0.015 liters ) 2.9 M NaOH = moles NaOH/0.015 liters = 0.0435 moles of NaOH
