How many moles are in 56 grams of carbon monoxide?
moles = weight in grams / molecular weight = 56 / 28 = 2 moles
How many grams are in 5.2 moles of magnesium sulfide?
Mass in grams = no of moles x molecular mass. So, mass in grams = 5.2x 56 = 291.2g

How many moles of aluminum are present in an aluminum cylinder with a mass of 15 g?
The Answer is.56 moles OR 0.56 moles
How many moles of CCL4 are there in 56 grams?
Divide the Molar Mass of C and Cl4 by 56 to get your awnswer!
56 grams equal how many micrograms?
m = ( 56 g ) ( 10^6 micg / 1 g ) = 5.6 x 10^7 micg <------------------------------
How many moles are present in 34 grams of KOH?
Depending upon how precise your masses are, KOH has a molar mass of about 56, so your answer is about 34/56.
How many grams are in 5.2 moles of magnesium sulfide?
Mass in grams = no of moles x molecular mass. So, mass in grams = 5.2x 56 = 291.2g
How many moles are in 3.4 10 to the power of 23 molecules of H2SO4?
Simply divide by the number that signifies moles of any thing; Avogadro's number. 3.4 X 10^23/6.022 X 10^23 = 0.56 moles of H2SO4
How do you calculate the number of moles in 56 millimole Na-OH?
Milli means one thousandth. So there are 1000 millimoles in a mole. Therefore 56/1000 gives you 0.056 moles.
