How many grams are in 0.02 moles of beryllium iodide

Beryllium iodide is BeI2. The molecular weight of BeI2 is 2(9.01) + 126.90 = 144.92g/mol. So, in 0.02 moles of BeI2, you have 0.02 * 144.92 = 2.9 grams (3 g if you want to stick to significant figures)

Answerd. may include all of these are many definitions of bases: the  brønsted-lowry definition of acids and bases says that bases are proton acceptors.the arrhenius definition of acids and bases says that bases increase [oh⁻] in solution (thereby producing oh⁻ ions)the lewis definition of acids and bases says that bases donate electron pairs.therefore, the sensible answer is that a base may include all of the described characteristics.
