Calculate the molarity (M) if 3.35g of H3PO4 is dissolved in water to give a total volume of 200mL

lyudmila [28]

Answer:

0.171 M

Explanation:

Step 1: Given data

Mass of H₃PO₄ (solute): 3.35 g

Volume of solution (V): 200 mL

Step 2: Calculate the moles of solute

The molar mass of H₃PO₄ is 97.99 g/mol.

3.35 g × 1 mol/97.99 g = 0.0342 mol

Step 3: Convert "V" to liters

We will use the conversion factor 1 L = 1000 mL.

200 mL × 1 L/1000 mL = 0.200 L

Step 4: Calculate the molarity of the solution

We will use the definition of molarity.

M = moles of solute / liters of solution

M = 0.0342 mol/0.200 L = 0.171 M

What is the Molar Mass of methylammonium bromide: Use the Periodic Table and round to the nearest hundredths.

egoroff_w [7]

The molar mass of methylammonium bromide is 111u.

<h3>What is molar mass?</h3>

The molar mass is defined as the mass per unit amount of substance of a given chemical entity.

Multiply the atomic weight (from the periodic table) of each element by the number of atoms of that element present in the compound.

Add it all together and put units of grams/mole after the number.

Atomic weight of H is 1u

Atomic weight of N is 14u

Atomic weight of C is 12u

Atomic weight of Br is 79u

Calculating molar mass of $2H_3NCH_3Br$ =2(1 x3+ 14+12+ 1 x 3 +79) = 111u

Hence, the molar mass of methylammonium bromide is 111u.

4. Why do compounds form in nature?

frez [133]

so basically a atom type contains the same number of protons. Chemical bonds put elements together to form more complex molecules called compounds. A compound consists of two or more types of elements held together by covalent or ionic bonds. Elements can't be divided into smaller units not using large amounts of energy.

499 mg sample of CuSO4. xH2O is heated and reweighed to give a mass of 319 mg. Given that the sample contains 2 mmol of Cu; what

nevsk [136]

The value of x in CuSO4. xH2O is 5.

Given that;

Number of moles of anhydrous salt = Number of moles of hydrated salt

Number of moles of anhydrous salt = 319 × $10^-3$

Mass of hydrated salt = 499 × $10^-3$ g

Number of moles of anhydrous salt = 319 $10^-3$ g/160 g/mol = 0.00199 moles

Number of moles of hydrated salt = 499 × $10^-3$ g/ 160 + 18x

0.00199 = 499 × $10^-3$ g/ 160 + 18x

0.00199 (160 + 18x) = 499 × $10^-3$

0.318 + 0.036x = 0.499

0.036x = 0.499 - 0.318

0.036x = 0.181

x = 0.181/0.036

x = 5

Hence, x in CuSO4. xH2O is 5.
