molarity conversion

For every molarity problem given do you have to always convert mL to liters since molarity is the concentration of solute per LITER of solution?

hi stuck again

According to the following equation, 0.750 g of C6H9Cl3 is mixed with 1.000 kg of AgNO3 in a flask of water. A white solid, AgCl, completely precipitates out. What is the mass of AgCl produced? C6H9Cl3 + 3AgNO3 ---> AgCl + C6H9(NO3)3. Molar Mass: C6H9Cl3 (187.50 g/mol), 3AgNO3 (169.88 g/mol), AgCl (...

Re: Limiting reactants product of moles

so then it would be 10 moles?

Limiting reactants product of moles

How many moles of CO2(g) are produced when 1 kg of CaCO3(s) is used to neutralize an acid spill? The equation for the reaction at 1 atm and 25 degrees C is: CaCO3(s) + H2SO4(aq) ---> CaSO4(s) + CO2(g) + H2O(l) I got really stumped while working out this problem and can't seem to get past it. I was w...

This question from the post assessment

5 g of reactant A reacts with 7 g of reactant B to produce 14 g of product. Is this possible?

Limiting reactants step 4

In lecture today, Lavelle went over limiting reactants for the example of calcium carbide reacting w/ water to form calcium hydroxide and ethyne. For step 4 for calculating the molar mass after the equation has been balance, why aren't coefficients included in finding the molar mass of the reactants...

Sig Figs

Do you guys think that if we're off by one sig fig the question will be counted as wrong on the test? I know that we should be pretty precise and constant with the # of sig figs because he'll be giving us all the same periodic table but do you think we'd be given partial credit?
