Find the mass in grams of 1.54 moles of H2O?
1.54 moles H2O (18.016 grams/1 mol H2O ) =27.7 grams
How do you find the number of moles that will react with 5 grams of butane?
We need to know the number of moles of WHAT is to react with the butane to provide you with an answer.
How many milligrams are in 68 grams?
68,000mg Find this value by converting grams to milligrams. Remember that the relationship is 1000mg = 1g.
How do you convert 1.42 kg to moles?
You have to first convert Kilos to grams. 1.42 kilos is 1420 grams. Next you have to find out the molecular weight (can be added up from the periodic table). Now divide grams by molecular weight to get your final answer in moles.
Need to find the weight in grams of 2 mole percent H2O?
Since 2 moles H2O weight 36 grams: this is the answer.
How many moles are in 89.0 grams of aluminum?
all you have to do to fine the moles of any element is divide the given grams by the molar mass (which you can find on a periodic table of elements) Likewise, if you need to find the grams, just multiply the number of moles by molar mass. moles = grams/molar mass grams = moles x molar mass your equation should look like this: moles = 89.0 / 17.0 moles = .471
Find the mass in grams of 1.54 moles of H2O?
1.54 moles H2O (18.016 grams/1 mol H2O ) =27.7 grams
How do you find 1.1 grams of feci3 In moles?
FeCl3 ? 1.1 grams FeCl3 (1 mole FeCl3/162.2 grams) = 0.0068 moles of FeCl3 ------------------------------------
0.871 moles is how many grams?
Multiply the number of moles by the molecular weight of the compound (or atomic weight for an element) to find the mass in grams.
Empirical formula for a compound that contains 32.2 percent Ca and 67.8 percent N by mass?
Assume the compound has a molar mass of 100 grams, from the information given, 32.2 grams is Calcium and 67.8 grams is Nitrogen.You then find the moles of each, which would be moles of Ca and moles of N.Dividing the two moles gives you the mole fraction: which we approximate to 6. This means that for every 1 mole of Ca, there are 6 moles of N, thus the answer is
How many moles are in 57 grams of Xenon?
To find the number of moles in 57 grams of Xenon, divide the given mass (in grams) by the molar mass of Xenon. The molar mass of Xenon is 131.3 grams/mol. Therefore, 57 grams of Xenon is equal to 0.434 moles (57/131.3).
How many grams does 5.60 x 1022 molecules of SiO2?
To find the mass, we divide by Avogadro's number to find the amount of moles. We then multiply the moles by the molar mass of the compound which is 60.08 grams. Doing all of this, we get a mass in grams of 5.59 grams.

How do units work in dimensional analysis?
in dimensional analysis (for chemistry) your usually converting substances to moles or grams to figure out whatever you need for the problem. For units, you always want the units to cancel out as 1/7 * 7 cancels out to 1/1 or 1.for example, if i want to find the molar mass of 3.00 moles of Carbon (C), this is your set up:(3.00 moles Carbon)(36.03 grams Carbon/1mole Carbon)=108.09/1 grams Carbon=108 grams Carbon(using sig. figs)in the problem above, since moles are the numerator, and you want to find how many grams are in 3 moles of carbon, you want to set up a ratio of moles per grams. Ratios can be flip flopped based on which units you need. So i look at the periodic table and see there are 12.01 grams per 1 mole, setting the ratio up so that when it multiplies 3 moles of carbon, the moles cancel and im left with grams of carbon, the units i want. It seems complicated but gets easier with practice.
What is the number of moles of argon in 607 g of argon?
the equation is Xg multiplied by the moles/grams of X = moles of X (the grams cancel leaving you with moles) 607g Ar x 1 mole/ 39.95g = 15.19 moles
How do you find the number of moles that will react with 5 grams of butane?
We need to know the number of moles of WHAT is to react with the butane to provide you with an answer.
How many moles grams are in 24.6 moles of Fe?
Find iron (Fe) on the periodic table the biggest number (at the bottom) is the mass number 1 mole is that number in grams. you can work it out from there.
