Answer to Question #322846 in General Chemistry for Karaigan

Question

Merchants usually sell small nuts, washers, and bolts by weight (like jelly beans!) rather than by individually counting the items. Suppose a particular type of washer weighs 0.120 g on the average.

1. What would 62 such washers weigh?
2. g
3. How many washers would there be in 105 g of washers?
4. washers

Answer 1

Weight of 62 washers= 0.120×62

=7.44g

No of washers in 105g= 105÷0.120

= 875 washers
