I believe is 8.9 if rounded to the nearest hundredth but if not I’ll give it the whole answer and round to whatever is asking you the whole answer is 8.9399375975
A buffer system usually will need a weak acid, like H2CO3, which is carbonic acid, and a strong base, and the only compound that could figure a fairly strong base among the options given is Na2CO3. NH3 and NaHCO3 are weak bases and HF is a strong acid. Therefore the best answer will be letter A
We are given the mineral ilmenite with a molecular formula of FeTiO3. The molar mass of the compound is equal to 151.72 g/mol. The percent titanium thus is 31.55 percent.when 750 grams of titanium is present, the mass of ilmenite is equal to 2377.18 grams
