Achemist needs 1.36 mol of strontium bromide, srbr2, for a reaction. what mass of strontium chloride should the chemist use?

336.5 grams

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number of particles.

convert given masses into moles.

Number of Moles =

Given number of moles = 1.36

Molar mass of = 247.43 g/mol

Putting in the values we get

Thus mass of strontium bromide used should be 336.5 grams.

that tool would be a compass
