Ans: 1.4 moles

<u>Given:</u>

Mass of tungsten = 250 g

<u>To determine:</u>

Moles of Tungsten

<u>Explanation:</u>

# moles of a given substance = Mass of the substance in grams/molar mass (g.mol-1)

Atomic mass of W = 184 g.mol-1

# moles of W = 250 g/184 g.mol-1 = 1.359 moles

Suppose you carry out a titration involving 3.00 molar HCl and an unknown concentration of KOH. To bring the reaction to its end
snow_tiger [21]

Answer: The concentration of the KOH solution is 1.01 M

Explanation:

According to neutralization law:

n_1M_1V_1=n_2M_2V_2

where,

n_1 = basicity of HCl = 1

n_2 = acidity of KOH = 1

M_1 = concentration of HCl = 3.00 M

M_2 = concentration of KOH = ?

V_1 = volume of HCl = 35.3 ml

V_2 = volume of KOH = 105.0 ml

Putting the values we get:

1\times 3.00\times 35.3=1\times M_2\times 105.0

M_2=1.01

Thus the concentration of the KOH solution is 1.01 M

what pressure will be needed to reduce the volume of 77.4 l of helium at 98.0 kpa to a volume of 60.0 l? 76 kpa 126 kpa
nekit [7.7K]
The system follow the Boyle's Law:

P_1\cdot V_1 = P_2\cdot V_2\ \to\ P_2 = \frac{P_1\cdot V_1}{V_2} = \frac{98\ kPa\cdot 77.4\ L}{60.0\ L} = \bf 126.4\ kPa
