The answer is 0.12626 kg.
To solve the problem, we need to use the formula:
mass = density x volume
We are given the density of platinum as 21.40 g/cm3 and the volume as 0.0059 L. However, we need to convert the volume from L to cm3 to match the units of density.
1 L = 1000 cm3
So, 0.0059 L = 5.9 cm3
Now we can substitute the values into the formula:
mass = 21.40 g/cm3 x 5.9 cm3
mass = 126.26 g
mass = 0.12626 kg (since 1 kg = 1000 g)
Therefore, the mass of 0.0059 L of platinum is 0.12626 kg.
