# What is the mass of 7.2 moles of titanium to the nearest tenth?

##### 1 Answer

#### Explanation:

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 **one mole** of titanium has a mass of

Now that you know the mass of one mole of titanium, you can calculate the mass of **moles** by using the metal's molar mass as a *conversion factor*

#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)|)))#
