Answer:
852g
Explanation:
From the question given, we obtained the following information:
Molarity = 3M
Volume = 2L
Mole =?
First, we need to find the number of mole of Na2SO4 present in 2L of the solution. This is achieved by doing the following:
Molarity = mole /Volume
Mole = Molarity x Volume
Mole = 3 x 2 = 6moles
Next, we'll find the molar mass of Na2SO4, as illustrated below:
Molar Mass of Na2SO4 = (23x2)+32+(16x4) = 46 + 32 + 64 = 142g/mol
Recall:
Number of mole = Mass /Molar Mass
Mass = number of mole x molar Mass
Mass = 6 x 142 = 852g

Answer:
Pentan_1,5_di-al
Explanation:
OHC-CH₂-CH₂-CH₂-CHO
This is Pentan_1,5_di-al
If we break this compound, we will observe that there is presence aldehyde group and hence the functional group "al". This aldehyde is bonded to carbon 1 and carbon 5 respectively.
Also the pentan is due to presence of 5 carbon atoms.
Therefore, the IUPAC name of this compound (OHC-CH₂-CH₂-CH₂-CHO) is Pentan_1,5_di-al
Answer:
P = 741.7 Pa
Explanation:
Pressure:
It is the force applied on object per unit area. The force is applied perpendicular to the surface.
Mathematical expression:
P = F/A
P = pressure
F = force
A = area
Given data:
Weight = 178 N
Area = 10 cm × 24 cm
Pressure = ?
Solution:
Area = 10 cm × 24 cm
Area = 240 cm²
Area = 240 /10000 = 0.024 m²
Formula:
P = F/A
P = 178 N / 0.024 m²
P = 741.7 Nm⁻²
Nm⁻² = Pa
P = 741.7 Pa
