How many atoms of Mg are there in the following equation? 3MgSO4

Group of answer choices

1

12

3

4

theres 4

Step-by-step explanation:

i know this because if it starts with a problem

like that one the number of atoms come after like water does

there 2 hydrogen and 2 oxygen no oxygen doesnt have a 2 after because oxygen is made up of 2 atoms so its just H2O

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

0.84 dang lotta people are looking for this lol or if you round up its 1 but the overall answer to that is 0.84
