The mass in grams of 1.4 mol of tungsten (W) is 257.4grams.

MASS CALCULATION:

  • The mass of a substance can be calculated by multiplying the number of moles of the substance by its molar mass. That is;

Mass of substance = molar mass × no. of moles

  • According to this question, there are 1.4 moles of tungsten. The molar mass of tungsten is 183.85g/mol

Mass of W = 183.85 × 1.4

Mass of W = 257.4grams.

Therefore, the mass in grams of 1.4 mol of tungsten (W) is 257.4grams
