What is the mass of 2.70 moles of magnesium chloride, mgcl2?

The mass of magnesium chloride is 257.1 grams.

Explanation:

To calculate the mass of magnesium chloride for given number of moles, we use the equation:

We are given:

Moles of magnesium chloride = 2.70 moles

Molar mass of magnesium chloride = 95.21 g/mol

Putting values in above equation, we get:

Hence, the mass of magnesium chloride is 257.1 grams.

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
