Question

Chalk contains 3% of carbon , 10% of calcium and 12% of oxygen. Find the amount in grams of each of these substances in 1 kg of chalk​...​

Answer 1

Answer:

From the question,

From the question,The amount of chalk =1 kg=1000 g

From the question,The amount of chalk =1 kg=1000 gWe have,

From the question,The amount of chalk =1 kg=1000 gWe have,Amount of carbon in it =3% of 1000 g

From the question,The amount of chalk =1 kg=1000 gWe have,Amount of carbon in it =3% of 1000 g=(3/100)×1000

From the question,The amount of chalk =1 kg=1000 gWe have,Amount of carbon in it =3% of 1000 g=(3/100)×1000=(3×10)

From the question,The amount of chalk =1 kg=1000 gWe have,Amount of carbon in it =3% of 1000 g=(3/100)×1000=(3×10)=30 g

From the question,The amount of chalk =1 kg=1000 gWe have,Amount of carbon in it =3% of 1000 g=(3/100)×1000=(3×10)=30 gAmount of calcium in it =10% of 1000 g

From the question,The amount of chalk =1 kg=1000 gWe have,Amount of carbon in it =3% of 1000 g=(3/100)×1000=(3×10)=30 gAmount of calcium in it =10% of 1000 g=(10/100)×1000

From the question,The amount of chalk =1 kg=1000 gWe have,Amount of carbon in it =3% of 1000 g=(3/100)×1000=(3×10)=30 gAmount of calcium in it =10% of 1000 g=(10/100)×1000=(10×10)

From the question,The amount of chalk =1 kg=1000 gWe have,Amount of carbon in it =3% of 1000 g=(3/100)×1000=(3×10)=30 gAmount of calcium in it =10% of 1000 g=(10/100)×1000=(10×10)=100 g

From the question,The amount of chalk =1 kg=1000 gWe have,Amount of carbon in it =3% of 1000 g=(3/100)×1000=(3×10)=30 gAmount of calcium in it =10% of 1000 g=(10/100)×1000=(10×10)=100 gAmount of oxygen in it =12% of 1000 g

From the question,The amount of chalk =1 kg=1000 gWe have,Amount of carbon in it =3% of 1000 g=(3/100)×1000=(3×10)=30 gAmount of calcium in it =10% of 1000 g=(10/100)×1000=(10×10)=100 gAmount of oxygen in it =12% of 1000 g=(12/100)×(1000)

From the question,The amount of chalk =1 kg=1000 gWe have,Amount of carbon in it =3% of 1000 g=(3/100)×1000=(3×10)=30 gAmount of calcium in it =10% of 1000 g=(10/100)×1000=(10×10)=100 gAmount of oxygen in it =12% of 1000 g=(12/100)×(1000)=(12×10)

From the question,The amount of chalk =1 kg=1000 gWe have,Amount of carbon in it =3% of 1000 g=(3/100)×1000=(3×10)=30 gAmount of calcium in it =10% of 1000 g=(10/100)×1000=(10×10)=100 gAmount of oxygen in it =12% of 1000 g=(12/100)×(1000)=(12×10)=120 g
