Question

What is the total number of grams of H20 produced when 116 grams of the product, Naci, is formed?

A) 36 9g
B) 54 9
C) 18 g
D) 9.0 g

Answer 1

A) 36 g

Step-by-step explanation:

From the source, some values have been correct.

Given that;-

Mass of NaCl formed = 116 grams

Molar mass of NaCl = 58 g/mol

Moles of NaCl =
`(Mass)/(Molar\ mass)=(116)/(58)\ mol=2\ mol`

According to the reaction shown below:-

`HCl+NaOH\rightarrow NaCl+H_2O`

1 mole of NaCl and 1 mole of
`H_2O` are produced upon reaction.

So,

2 moles of NaCl and 2 moles of
`H_2O` are produced upon reaction.

Moles of water = 2 moles

Molar mass of water = 18 g/mol

Mass =
`Moles* Molar\ mass=2* 18\ g=36\ g`

36 g of
`H_2O` is produced.
