Element A has a mass of 0.444 grams and reacts with Element B via a combination reaction. The mass of the product is 0.988 grams. The molar mass of Element A is 111 g/mol and the molar mass of Element B is 68 g/mol.

How do you convert mass to moles?

A procedure calls for the bromination of 12 mmol of trans‑cinnamic acid with 12 mmol of Br 2 in glacial acetic acid solvent. Select the likely consequence of accidentally using 6 mmol of Br 2 instead.

Let us assume that cu (oh) 2 (s) is completely insoluble, which signifies that the precipitation reaction with naoh (aq) (presented in the transition) would go to completion. cu2 + (aq) + 2naoh (aq) → cu (oh) 2 (s) + 2na + (aq) if you had a 0.
