how many grams of copper hydroxide can b prepared from 2.7g of copper (II) nitrate and excess sodium hydroxide?

Answer 1

Write the equation and balance it.

Convert 2.7 g Cu(NO3)2 to moles. moles = grams/molar mass.

Using the coefficients in the balanced equation, convert moles copper(II) nitrate to moles copper(II) hydroxide.

Finally, convert moles copper(II) hydroxide to grams. grams = moles x molar mass.
