How many moles of Al2S3 are in 100 g of Al2S3?
100/150.158 is 0.666 moles
How do you find the concentration of 3.50g of potassium chromate in 100 ml water?
K2CrO4 Molarity (concentration) = moles of solute/Liters of solution (100 ml = 0.100 Liters ) Find moles K2CrO4 first. 3.50 grams = (1 mole K2CrO4/194.2 grams) = 0.01802 moles K2CrO4 ----------------------------------------------next Molarity = 0.01802 moles K2CrO4/0.100 Liters = 0.180 M K2CrO4 -------------------------
Ph solution by 2 numbers change in hydrogen ions by?
The pH numbers refer to power of ten, so a change of 2 numbers means that the moles per liter of hydrogen ions has changed by 100.
How many moles of KBR are there in 100 mL if a 0.75 M Solution?
There would be 0.75 moles in 1 liter of solution. You have 100 mL which is in fact 0.1 liters. so you would have 0.1 of 0.75 moles. 0.1 x 0.75 = 0.075 moles.
5.8 grams in 1 liter of water equals how many moles?
if you have 100 liters how many moles does that equal?
How many moles of sodium borohydride are used in 100 mg?
.0104 mol
3M sodium hydroxide?
C2H4O2 + NaOH = H2O + C2H3O2Na Acetic acid (60 gm) + sodium hydroxide ( 40 gm) = 100 gm water (18 gm) + sodium acetate (82 gm) = 100 gm Ratio reactants to products = 1:1 Molarity = moles / L, 3M = 3 moles / 1 L Acetic acid = 60 gm / total reactant 100gm = 1.8 moles Multiply by 3 = 1.8 moles or 180 grams Sodium Hydroxide = 40 gm / total reactant 100 mg = 1.2 moles or 120 grams. 180 grams acetic acid + 120 grams sodium hydroxide = 300 grams. 300 grams divided by 1 liter = 3M So in order to make 3 M sodium acetate combine solution, add 180 grams acetic acid and 120 grams sodium hydroxide with 1 liter of water.
Which would lower the freezing point more 100 moles of sugar or 100 moles of NaCl?
100 moles of NaCl
Calculate the mass of solid needed to make the solution 100 ml of solution that is 1.0 M in sodium cation using sodium chloride?
100ml is 0.1 litres, so you need 0.1 moles of sodium chloride.
How do you find the average of 100 numbers?
The average is the sum of those 100 numbers divided by 100.
How many moles of Al2S3 are in 100 g of Al2S3?
100/150.158 is 0.666 moles

How many moles of water are there in 1.792 L?
95,474 moles
Take 2 numbers if you add both the numbers you get 100 and the difference is also 100 find the number?
0 and 100.
If 156 g of sodium nitrate react and 112 grams of sodium nitrate are recovered what is the percentage yield?
Moles NaNO3 = 156 g / 84.9965 g/mol = 1.84 we would get 1.84 moles of NaNO2 => 1.84 mol x 68.9965 g/mol = 127 g % = 112 x 100 / 127 = 88.2
