What is the percentage of limestone on earth?
Probably about 80%. This is what I have heard and learnt.
What is the mass in grams of 2.50 mol of sulfur?
Sulfuric acid has a molecualr weight of 98 and so 2.5 moles would weigh 245 g
How many grams of Mg must react with HCl in order to produce 80 mL of hydrogen gas at STP?
The key is to understand that Mg is limiting. Therefore, the final number of moles of H2 will equal the starting number of moles of Mg. Using gas law equations we can first find the moles of H2 and then find the moles of Mg. 1. PV = nRT --> n = PV/RT P = 760 mm Hg (pressure at STP) V = 80.0 mL (given) R = 62,400 mL-mm Hg/mol-K (constant) T = 273 K (temp. at STP) Now you have all the information you need to solve for the number of moles of Mg. Solve for moles and convert to grams.
How many grams of liquid water are produced when 60 grams of ice melt?
when 60 grams of ice melts , there will be 60 grams of liquid water left.
What is the mass of 2.50 moles of oxygen gas?
The relationship between number of moles and mass is: n = m/MW Where n is the number of moles, m is the mass in grams and MW is the molecular weight (or molecular mass). Subsituting the numbers into the equation: 2.5 mol = m/32 (from O2(g), 16 from each oxygen) m = 2.5 * 32 = 80 grams This also means that there is approximately 1.5 x 1024 molecules of O2 in your sample.
What is the mass in grams of 1.12 moles of SO3?
molar mass SO3 = 80 g/mole. 1.12 moles x 80 g/mole = 89.6 grams
How many liters of C2H2 should be produced from 80 grams of H2O?
Need an equation as this is not familiar to me. Where is the carbon coming from? Moles? Molarity. All info I do not have.
How many moles are in each what 80.0g of NaOH?
2 moles 80/40= 2
How many grams are there in 80 milligrams?
80 milligrams8 centigrams0.8 decigrams0.08 grams
How much NaOH is in 3.8 L of a 0.53 M NaOH solution?
Molarity = moles of solute/volume of solution 0.53 M NaOH = moles NaOH/3.8 Liters = 2.014 moles, or about 80 grams
How many cups are in 80 grams of batter?
80 grams is 1/3 cup
How many grams are in 80 pounds?
80 g = about 0.1764 pounds.
How many moles in 8200G of Fe?
The molecular mass of iron(III) chloride is 55.8 + 3(35.5) = 162.3 Amount of iron (III) chloride in a 80.5g pure sample = 80.5/162.3 = 0.496mol
How many grams are in 80 mg?
0.08 grams
What is the molarity of 80g magnesium chloride dissolved in 250ml of water?
MgCl2 Molarity = moles of solute/Liters of solution ( 250 ml = 0.250 L ) Get moles MgCl2 80 grams MgCl2 (1 mole MgCl2/95.21 grams) = 0.8402 moles MgCl2 Molarity = 0.8402 moles MgCl2/0.250 Liters = 3.4 M MgCl2 ----------------
What is the percentage of limestone on earth?
