`4.62 g` of sugar and `2.935 g` off table salt were mixed with `28.2 g` of water. What is the properly reported mass of the solution ?

Text Solution

Verified by Experts

Mass of sugar `= 4.62 g`
Mass of table salt `= 2.935 g`
Mass of water `= 28.2 g`
Add : Total mass of solution `= 35.755 g`
The final result has to reported upto one decimal place. The correct answer is obtained by dropping digits 5 and 5 one by one and also by applying 'rounding off' principle
`:.` The correct answer `= 35.8 g`.
