Add 1299 g and 45.1 kg and express your answer in milligrams (mg) to the correct number of significant figures. a) 4.64 x 10t mg b) 4.64 x 10s mg c) 4.64 x 10s mg d) 4.64 x 10' mg

4.64 × 10^7 mg

Explanation:

Given:

T =1299g + 45.1kg

Convert kg to g

T = 1299g + 45.1kg ×1000g/kg

T = 1299g + 45100g

T = 46399g

T= 4.64 × 10^4 g

Convert to milligram

T = 4.64 × 10^4 g × 1000mg/g

T = 4.64 × 10^7 mg

Therefore, 1299g + 45.1kg = 4.64 × 10^7 mg
