Final answer:
To find the mass of each of the 19 cups made from 1 kg 530 g of silver, convert the mass to grams (1530 g) and divide by 19, resulting in each cup weighing approximately 80.5 g.
Step-by-step explanation:
To find out the mass of each cup made out of 1 kg 530 g of silver, first convert the total mass of silver to grams and then divide by the number of cups. To convert kilograms to grams, use the conversion factor of 1 kg = 1000 g.
First, convert 1 kg 530 g to grams:
Now, divide the total mass by the number of cups:
The mass of each cup is approximately 80.5 g when rounded to the nearest tenth of a gram, as is common practice when reporting measurements that involve precision.
