Question

D. Calculate the molecular mass of the
following in u.
a. NH, b. CH,COOH c. C,H,OH with explanation reply fast PLS​

Answer 1

Answer:

(a) N=14

H=1

Molecular mass=15

(b) 2C=12*2=24

2H=2

2O=32

Molecular mass=58

(c)C=12

2H=2

O=16

Molecular mass=30

Answer 2

Answer:

(a) 15u (b) 58u (c) 30u

Explanation:

(a) in NH N contain 14 atom and H contain 1 atom= 15u

(b) in CHCOOH carbon contain12 atom but here 2 carbon show 12×2=24 .oxygen here 2 and contain 16 atom,16×2=32.

abd hydrogen2 contain 1 atom,1×2=2. answer is 2+32+24=58u

(c) CHOH hydrogen two =2

oxygen contain 16 element.=16

carbon contain 12 element

answer 2+12+16=30u
