Calculate the molarity of a solution prepared by dissolving 12.5 g of Na2CrO4 in enough water to produce a solution with a volum
gregori [183]

Answer:

0.0953M

Explanation:

First, let us calculate the number of mole present in 12.5g of Na2CrO4.

Molar Mass of Na2CrO4 = (23x2) + 52 +(16x4) = 46 + 52 +64 = 162g/mol

Mass of Na2CrO4 = 12.5g

Number of mole =?

Number of mole =Mass /Molar Mass

mole of Na2CrO4 = 12.5/162 = 0.0772mol

Now, we can calculate for the molarity as follows:

Mole = 0.0772mol

Volume = 810mL = 810/1000 = 0.81L

Molarity =?

Molarity = mole /Volume

Molarity = 0.0772mol/0.81L

Molarity = 0.0953M

Name two traits of pseudoscience
lions [1.4K]
Pseudoscience refers to belief, theories and practices that claims to be scientific but which have no basis in scientific facts.
Pseudoscience has many traits two of which are:
1. It is based on dogma and uncritical belief. Counter evidence might draw hostility from pseudo scientists.
2. There is usually suppression or distortion of data. Pseudo scientists typically perform selective data gathering, in which they only gather and consider favorable data that support their claims. <span />
