What is the mass of 6.78x1050 molecules of NaCl

ryzh [129]

Answer:

Explanation:

Molar mass of NaCl= 58.44 gm

So we got it that,

58.44 mass of NaCl contain = 6.023*10^23 molecules of Na Cl

x mass will contain = 6.78*10^50

by cross multiplication , we get

x= 58.44*(6.78*10^50)/ 6.023*10^23

x= 65.785 * 10^27 molecules

Please balance the equation, putting the correct coefficient in each box.

Mariulka [41]

Answer: $Bi(OH)_3+3HNO_3\rightarrow 3H_2O+Bi(NO_3)_3$

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The balanced equation will be:

$Bi(OH)_3+3HNO_3\rightarrow 3H_2O+Bi(NO_3)_3$
