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.
How many molecules are there in 60.0g of acetic acid C2H402?
Find the moles using the formula: moles= grams/molecular mass In this case, molecular mass = 24+4+32 = 60g/mol so 66/60 = 1.1 moles Then, using avogadro's constant, work out the number of molecules. n(molecules) = number of moles x 6.02x10^23 =1.1x 6.02x 10^23 =?
What is the number of atoms of beryllium in 36.0 g of Be?
First work out the moles So do 36g / 80 (80 is bromine's relative atomic mass number) You have 0.45 M Then, do 0.45 * 6.02*10^23 You get 2.7*10^23, which is your answer
What is the mass of 2.00 moles of carbon dioxide CO2?
to work out the number of moles, you divide the mass by the relative atomic mass so 200 divided by 44 = 4.55 moles
What is the difference between molarity and moles per liter of solvent?
Molarity has to deal with the concentration of solute in a concentration, and Moles per liter of the solvent is the concentration of solvent.
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.
How many grams are in moles of Li2O show work?
The molar mass of Li2O is 29,88 g (the sum of atomic weights of 2Li and 1O).
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.
How many moles of copper are present in 75.92 g?
The atomic mass of Copper is 63.5 grams One mole of any element has a mass equal to the atomic mass. 0.75 grams of Cu = x moles of Cu 63.5 grams of Cu = 1 mole of Cu Set up a proportion and solve for x Divide 0.75 / 63.5 = x /1 0.75 ÷ 63.5 = x

How many grams in 5.6 kg?
There are 5,600 grams in 5.6 kilograms. (To work out how many grams in kilograms, you multiply the grams by 1,000.)
What is the number of atoms of beryllium in 36.0 g of Be?
First work out the moles So do 36g / 80 (80 is bromine's relative atomic mass number) You have 0.45 M Then, do 0.45 * 6.02*10^23 You get 2.7*10^23, which is your answer
What is 487.0grams in milligrams with work shown?
There are 1000 milligrams in a gram. Therefore you have to multiply grams by 1000. 487*1000 is 487,000 milligrams.
What is the mass of 2.00 moles of carbon dioxide CO2?
to work out the number of moles, you divide the mass by the relative atomic mass so 200 divided by 44 = 4.55 moles
What is the difference between molarity and moles per liter of solvent?
Molarity has to deal with the concentration of solute in a concentration, and Moles per liter of the solvent is the concentration of solvent.
How many half grams grams in an oz?
Going back to my Drug dealing day's I used to work on 28.4 grams too the ounce. But that was many moons ago.
