# Mgcl2 strong electrolyte?

This is not a question. Yes MgCl2 is a strong electrolyte. Cl dissolves completely which makes it a strong electrolyte.

### How many milliliters of a M MgCl2 solution contain 17.5g MgCl2?

1 mole of MgCl2=95.21 grams (found on the periodic table) 17.5 g of MgCl2(1mole of MgCl2/95.21g of MgCl2)=.184 moles of MgCl2(grams cancel out and rounded to 3 sig. figs) .184 moles of MgCl2 (1 Liter/2.5 moles of MgCl2)=0.735L of MgCl2 (moles cancel and rounded to 3 sig figs) 0.735 L of MgCl2(1000 milliLiters/1 Liter)=73.5 mL of MgCl2 and round the answer to 2 sig figs which equals 74 milliLitersof MgCl2

### What is the mass of 1.5 moles of MgCl2?

The molar mass (mass of 1 mole) of MgCl2 is 95.205 g/mol. To determine the mass of 1.5 mol MgCl2, multiply the moles by the molar mass. Molar mass MgCl2 = (1 x 24.305 g/mol Mg) + (2 x 35.45 g/mol Cl) =95.205 g/mol MgCl2 1.5 mol MgCl2 x (95.205 g MgCl2)/(1 mol MgCl2) = 150 g MgCl2 (rounded to two significant figures)

### How many grams make up 1.5 moles of MgCl2?

The molar mass (mass of 1 mole) of MgCl2 is 95.205 g/mol. To determine the mass of 1.5 mol MgCl2, multiply the moles by the molar mass. Molar mass MgCl2 = (1 x 24.305 g/mol Mg) + (2 x 35.45 g/mol Cl) =95.205 g/mol MgCl2 1.5 mol MgCl2 x (95.205 g MgCl2)/(1 mol MgCl2) = 150 g MgCl2 (rounded to two significant figures)

### What is the mass of 4.30moles of magnesium chloride MgCl2?

409g MgCl2 The mass of one mole (or molar mass) of magnesium chloride is 95.205g/mol. Multiply the molar mass of magnesium chloride times 4.30mol, which gives 409.3815g of magnesium chloride. Since 4.30 has three significant figures, round 409.3815g to 409g magnesium chloride. 4.30mol MgCl2 x 95.205g MgCl2/mol = 409.3815g MgCl2 (round to 409g MgCl2 due to significant figures)
