How
many grams of AgNO3 are required to make 770.0 mL of a 0.15 M
solution?
How many grams of AgNO3 are required to make 770.0 mL of a 0.15 M solution? The molar mass of silver nitrate is 169.9 g/mol. One approach is to solve the molarity relationship (M- n/N) for moles. o a 19.6g b. 6.82 g O5.10 g o d. 1.95 g O e. None of the above
7. How many grams of chlorous acid must be dissolved in water to make 100 mL of a HClO2 solution whose pH is 2.40? Ka for HClO2 = 1.1 x 10-2. Molar mass of HClO2 = 68.5 g/mol.
please solve
2. How many grams of NaNO3 solids are required to make a 100.0 mL of solution containing 1000. ppm of NO; (not NaNO )? 3. Assume the soil contains 25 ppm of nitrate (not N), how many grams of nitrate in every 0.500 grams of soil? 4. If we mix 0.500 grams of soil containing 25 ppm nitrate with 10 mL of water and assume all nitrate in soil dissolves in water, how many ppm of nitrate in...

CzHg +502 3CO2 + 4H20 Question 34 2 pts How many mols of reactant remains after 0.47 mol of sodium phosphate reacts with 0.54 mol of magnesium chloride? (Just put in the number - don't put the units in the answer.) 2NaPO, (aq) + 3MgCl2 (aq) + 4NaCl(aq) + Mg3(PO4)2 (s)...
How many grams of NaCl are in 191 mL of a 0.85 M NaCl solution? (The molar mass of NaCl is 58.44 g/mol.) Enter your numerical result in grams without the unit to a precision of 0.01 g.
How many grams of CaCl2 are needed to make 610.3 g of a solution that is 36.5% (mm) calcium chloride in water? Note that mass is not technically the same thing as weight, but (m/m) has the same meaning as (w/w). Number g Cac How many grams of water are needed to make this solution? Number b) What is the volume percent % v/ alcohol in 739 mL of water? (Assume that volumes are additive.) of an alcohol solution made...
How many grams of CaCl2 are needed to make 853.6 g of a solution that is 31.0% (m/m) calcium chloride in water? Note that mass is not technically the same thing as weight, but (m/m) has the same meaning as (w/w). How many grams of water are needed to make this solution? What is the volume percent % (v/v) of an alcohol solution made by dissolving 109 mL of isopropyl alcohol in 741 mL of water? (Assume that volume are...
How many grams NaOH (40.0 g/mol) are required to make 250 mL of a 0.500 M solution?
a) How many moles of Al2(SO4)3 are required to make 55 mL of a 0.050 M Al2(SO4)3 solution? (Hint, molarity is moles per liter. You know the molarity. You are given the number of mL's, which can be converted to liters. Just set it up so the units cancel and you get "moles".) moles Al2(SO4)3 b) What is the molecular weight of Al2(SO4)3, to the nearest gram? grams c) What mass of Al2(SO4)3 is required to make 55 mL of...
