1. 9.5g of magnesium chloride reacts with 8.0g of sodium hydroxide to form 5.8g of magnesium hydroxide. a) calculate the mass of sodium chloride produced
b) use the masses to calculate the moles of each substance, as the simplest whole number ratio. balance the equation below:
MgCL2 + NaOH ---> Mg(OH)2 + NaCL

When the water vapor cools it condenses select a number that represents his process on the

The osmotic pressure exerted by a solution is equal to the molarity multiplied by the absolute temperature and the gas constant r. suppose the osmotic pressure of a certain solution is measured to be 12.atm at an absolute temperature of 317k. write an equation that will let you calculate the molarity c of this solution. your equation should contain only symbols. be sure you define each symbol other than r. equation: c=? definition of symbols: ? = 12 atm ? = 317 k
