What mass of ilmenite (in grams) is required if you wish to obtain 450 g of titanium? the mass of percent of titanium is 31.6%

Mass of ilmenite=x
We can suggest this equation:
31.6% of x=450 
(31.6/100)x=450
x=(450*100)/31.6=1424.05

we need 1424.05 g of ilmenite to obtain 450 g of titanium. 

The answer should be vaporization 

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.
