To solve this problem, we have to apply mole-concept to this and we would need the molar mass of AlCl3. 2g of AlCl3 contains 9.034*10^21 molecules.
<h3>Number of Molecules in 2g of AlCl3</h3>
The molar mass of AlCl3 is given as 133.34g/mol
Data;
- mass = 2g
- molar mass = 133.34g/mol
Using the mole concept, we can equate the molar mass to the number of molecules present in the entity.

If we equate this

From the calculations above, 2g of AlCl3 contains 9.034*10^21 molecules.

Answer:
51/28
Step-by-step explanation:
Start by making common denominators.
<u>7</u> <u>2</u>
4 4
Now subtract the two.
7 - 2 = <u>5</u>
4
Now you have to make common denominators for the second part, 4/7
<u>16</u> + <u>35</u> = <u>51</u>

Horseshoe crabs are marine and brackish water arthropods. They live primarily in and around shallow coastal waters on soft sands.
45000 x 4 = 180,000
180,000 * 5 = 900,000 ml in 5 days
1 liter = 1000 ml
900,000 / 1000 = 900 liters of water
