in any of the numbers being multiplied or divided."

Multiplication and Division Examples

3.45 g / 45.001 ml

= .076664963 = .0767 g/ml (rounds to 3 sig figs)

341.12 kg / 512.905 L

= .665074429 = .66507 kg/L (rounds to 5 sig figs)

12.01 g ? 334 J/g

= 4011.34 J = 4010 J (rounds to 3 sig figs)

400 kg / 12 L

= 33.3333333 kg / L = 30 kg/L (rounds to 1 sig fig)

543.00 g / 137.2 ml

= 3.957725948 = 3.958 g/ml (rounds to 4 sig figs)

10,003 g ? 2,210 J/g

= 22,106,630 J = 22,100,000 J (rounds to 3 sig figs)
