題目如下 What is the true mass of water weighted at 24℃ in the air if the apparent mass is 1.034 6 ± 0.000 2 g? The density of air is 0.001 2 ± 0.0001 g/mL and the density of balance weights is 8.0 ± 0.5 g/mL. The uncertainty in the density of water in Table 2-7 is negligible in comparison to the uncertainty in the density of air Table 2-7相關內容如下 water at 24℃ density 0.997 299 5 volume of 1 g of water(ml) at temperature 1.003 8 請化學高手幫忙解答一下 真的看不太懂題意 謝謝 --
