Answer:
0.67 g
Explanation:
We know that 1 mole of an element is 6.02 x 10^(23) atoms
Now, arsenic has 5.49 × 10²¹ atoms
Thus;
Number of moles of arsenic = 5.49 × 10²¹ × 1/6.02 x 10^(23) = 9 × 10^(-3) moles
We are told that;
one mole of arsenic = 74.92 g.
Thus, 9 × 10^(-3) moles = 9 × 10^(-3) × 74.92/1 = 0.67428 g ≈ 0.67 g
Answer:
Blood is liquid and red, just like a red river. And for humans without blood there is no life because there is nothing to transport nutrients and oxygen to the body cells. Hence blood is the red river of life.
