Question

Chalk contains 10% Calcium, 3% Carbon and 12% Oxygen. Find the amount of

Carbon and Calcium (in grams) 2



kgs of chalk.​

Answer 1

Answer:

1kg=1000gram

1. Calcium(10%)= (10/100)*1000

=100 gram

2.carbon (3%)= (3/100)*1000

=30 gram

3. oxygen (12%)=(12/100)*1000

= 120 gram

Answer 2

ᴄᴀʀʙᴏɴ = 3/100 × 5/2

= 3/40 × 1000

= 75 ɢʀᴀᴍꜱ

ᴄᴀʟᴄɪᴜᴍ = 10/100 × 5/2

= 1/4 × 1000

= 250 ɢʀᴀᴍꜱ
