Data:
Arsenic Molar Mass = 74,9216 ≈ 75 u (<span>atomic mass unit)</span>
Solving:
1 mole of arsenic → 75g ------------ 6,02*10²³ molecules
..................................X -------------- 1 molecule
6,02*10²³X = 75
![x = \frac{75}{6,02*10^{23}}](https://tex.z-dn.net/?f=%20x%20%3D%20%5Cfrac%7B75%7D%7B6%2C02%2A10%5E%7B23%7D%7D%20)
Answer:
Arrhenius acid & Bronsted-Lowry acid
Explanation:
The units of ppm means parts per million. Also, It is equivalent to milligrams per liter. It is one way of expressing concentration of a substance. It u<span>sually used to describe the concentration of something in water or soil. We calculate the mass of CaCO3 as follows:
Mass = 75 mg/L (.050 L) = <span>3.75 mg CaCO3</span></span>
