What is the formula mass for #Sr(NO_3)_2#?

Answer 1

#211.64 g/(mol)#

#color(magenta)"We will use the formula below to answer the question:"#
atomic weight of element #xx#number of atoms given by subscript #=# formula mass

First, you want to have a periodic table available so you can determine the atomic weight of Sr, N, and O:

From the chemical formula, we have 1 strontium atom, so the atomic weight of Sr is just 87.62 g/mol.

There are 2 nitrogen atoms, so the atomic mass has to be multiplied by 2, which gives you a value of 28.02 g/mol

Next, you have 6 oxygen atoms, so you would multiply the atomic mass of O by 6 to obtain an atomic weight of 96.00 g/mol

Now you want to add the mass of each atom together to obtain the formula mass of the entire compound:

#color(purple) ("87.62 g/mol + 28.02 g/mol + 96.00 g/mol = 211.64 g/mol")#

Answer 2

To calculate the formula mass of Sr(NO₃)₂, you need to find the atomic masses of each element in the compound and then multiply them by the respective subscript in the formula.

Sr: 1 atom * 87.62 g/mol = 87.62 g/mol N: 2 atoms * 14.01 g/mol = 28.02 g/mol O: 6 atoms * 16.00 g/mol = 96.00 g/mol

Total formula mass = 87.62 g/mol + 28.02 g/mol + 96.00 g/mol = 211.64 g/mol

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
