Answer:
Microwatts.
Explanation:
RF + EMF Unit Conversion Charts: Interpreting exposure levels. When measuring Radio Frequencies, the most common units of measurement are microwatts per square meter (µW/m2), microwatts per square centimeter (µW/cm2) and volts per meter (V/m).
Mass of calcium carbonate (in grams) can be dissolved by 4.1 g of Hcl is 5.62g.
<h3>What is balanced equation?</h3>
A balanced equation is one for a chemical reaction in which the overall charge and the number of atoms for each component are the same for both the reactants and the products. In other words, the mass and charge of both sides of the reaction are equal.
The reaction between calcium carbonate and hydrochloric acid can be expressed through the chemical reaction,
CaCO₃ + 2HCl --> CaCl₂ + H₂O + CO₂
Hydrochloric acid has a molecular weight of 36.45 g/mol compared to calcium carbonate's molecular weight of 100 g/mol. According to the equation above, 72.9 g of hydrochloric acid may dissolve 100 g of calcium carbonate.
x = (4.1 g HCl)(100 g CaCO3 / 72.9 HCl)
x = 5.62 g.
