Question

Dau coroană! Repede!!!! Cu tot cu explicație.​

Answer 1

masa atomica(A) a carbonului este 12

12gC.......1molC....6,023•10²³ atomi C

360gC......x..............y

$x = \frac{360 \times 1}{12} = \frac{360}{12} = 30$

deci 30 moli C

$y = \frac{360 \times 6.023 \times 10 ^{23} }{12} = 30 \times 6.023 \times 10 ^{23} = 180.69 \times 10 ^{23}$

180,69•10²³ atomi C

Answer 2

Răspuns:

MC=12g/mol

n=360/12=30moli C

1mol C.........12g.........6, 022x10²³atomi

360g.........x atomi

x= 360x6, 022x10²³atomi /12=180,66×10²³ atomi C
