The atomic number of nitrogen is 7. what is the mass number of a nitrogen atom with 6 neutrons?

The mass number is 13

Explanation:

Mass number = Protrons + neutrons;

While Atomic number = Number of neutrons

Therefore, if the atomic number of nitrogen is given as 7, then its Protrons = 7

So, mass number = 7 + 6 = 13

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.

label a cell membrane

label b cytoplasm

label c ribosomes

label d dna

the membrane forms the outside of the cell

cytoplasm is the liquid within

ribosomes are the components within that distribute rna

the dna is the genetic make-up
