What is the mass of 7.2 moles of titanium to the nearest tenth?
The first thing to do here is to figure out the mass of one mole of titanium,
To do that, grab a periodic table and look for titanium. You'll find this metal located in period 4, group 4.
Notice that titanium has a molar mass equal to
Now that you know the mass of one mole of titanium, you can calculate the mass of
#7.2 color(red)(cancel(color(black)("moles Ti"))) * "47.867 g"/(1color(red)(cancel(color(black)("mole Ti")))) = "344.6424 g"#
The last thing to do here is round this off to the nearest tenth, which means leaving the answer rounded to one decimal place
#color(green)(|bar(ul(color(white)(a/a)color(black)("mass of 7.2 moles Ti " = " 344.6 g")color(white)(a/a)|)))#
