Answer:

0.0763 M NaOH solution

3.05 g/mol NaOH solution

Explanation:

NaOH + HCl ----> NaCl + H2O

1 mol 1 mol

M(NaOH)*V(NaOH) = M(HCl)*V(HCl)

M(NaOH) *86 mL = 0.0175M*375 mL

M(NaOH) = 0.0175M*375 mL/86 mL = 0.0763 M

0.0763 M = 0.0763 mol/L

M(NaOH) = 23 + 16 + 1 = 40 g/mol

0.0763 mol/L * 40 g/mol = 3.05 g/mol NaOH

calculate the volume occupied by 10g of propane gas, under normal conditions of temperature and pressure

andriy [413]

Answer:

5.5 L

Explanation:

First we convert 10 g of propane gas (C₃H₈) to moles, using its molar mass:

10 g ÷ 44 g/mol = 0.23 mol

Then we use the PV=nRT formula, where:

P = 1 atm & T = 293 K (This are normal conditions of T and P)

n = 0.23 mol

R = 0.082 atm·L·mol⁻¹·K⁻¹

V = ?

1 atm * V = 0.23 mol * 0.082 atm·L·mol⁻¹·K⁻¹ * 293 K

V = 5.5 L

What is the mass, in grams, of a liquid having a density of 1.50g/mL and a volume of 3500mL

mojhsa [17]

Answer:

5,250g

Explanation:

Density = Mass / Volume

*Note: mass = x

1.50g/mL = x / 3500mL

multiply 3500mL on both sides

1.50g/mL * 3500mL = 3500mL(x) / 3500mL

cancel units

x = 5250g
