A nickel compound has the formula Ni(NO3)2•xH,0 and a molar mass
Fofino [41]
<h2>Answer:  x = 6</h2>

Explanation:

Molar mass of a compound is the sum of the molar mass of all the atoms of the compound.

⇒ Molar mass of the Nickel Compound (Hydrated Nickel (II) Nitrate)

             = Molar mass (Ni+ 2N + 6O)+ x (2H+ O)

             = [58.693 +  2(14.007) + 6(15.999)] + x [2(1.008) + 15.999] g/mol

             = (182.701 + 18.015x) g/mol

Since the molar mass is known to be  290.7 g/mol

then  182.701 + 18.015x = 290.7

⇒                       18.015x =  290.7 - 182.701

                                    x =  (290.7 - 182.701) ÷ 18.015

∴                                   x = 6    [conventionally expressed as a whole number]

            that makes the compound Nickel Nitrate Hexahydrate

The chemical formula of ordinary sugar is C12H22O11. Calculate the mass of 7.35 mol of sugar.
ch4aika [34]

First, you need to find the mass of 1 mol of sugar. Mass, or molar mass, can simply be found by adding the masses of the individual elements. These are given to you on the periodic table.

C_{12}H_{22}O_{11}

12 x 12.011 grams (molar mass of Carbon) = 144.132 g

22 x 1.008 grams (molar mass of Hydrogen) = 22.176 g

11 x 15.999 grams (molar mass of Oxygen) = 175.989 g

Add all of the pieces together.

144.132 g + 22.176 g + 175.989 g = 342.297 grams

So, if one mole has 342.297 grams, then 7.35 of that amount will be your answer.

342.297 g/mol x 7.35 mol =  2,515.88 grams
