How many moles of mgsio3 are in 233 g of the compound?

M = 233g
M = 24 + 28+ 16 * 3 = 100g/mol

n = m/M = 233g / 100 g/mol = 2,33mol

They can measure  the amount of energy gained or lost

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.
