Use this table to match the molecules with their estimated masses. Atom Mass (in grams)
hydrogen 1.67 × 10-24
oxygen 2.66 × 10-23
carbon 1.99 × 10-23
nitrogen 2.32 × 10-23

7.31 x 10^-23

CO2 (1 atom of carbon and 2 atoms of oxygen)

3.34 x 10^-24

H2 (2 atoms of hydrogen)

2.821 x 10^-23

NH3 (1 atom of nitrogen and 3 atoms of hydrogen)

7.64 x 10^-23

NO2 (1 atom of nitrogen and 2 atoms of oxygen)

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.
