how many gram of potassium bromide can be made from 13.7 grams of potassium and unlimited bromide

  • CHEM -

    Write the equation and balance it.

    Convert 13.7 g K to moles. moles = grams/molar mass.

    Using the coefficients in the balanced equation, convert moles K to moles KBr.

    Now convert moles KBr to grams. grams = moles x molar mass.

  • CHEM -

    41.7 g KBr
