2. Would you measure a pencil in meters? A hallway in millimeters? Discuss
Eduardwww [97]

Answer:

Measuring a pencil in meters would be very difficult, as a single meter is much longer than one pencil. Also, measuring a hallway in millimeters would be very difficult considering how small millimeters are in comparison to a hallway. However, if you switch these two then they would work very well.

How many significant digits are in 89015
Lilit [14]

Answer:

Total 5 significant digits.

Explanation:

Significant digits are the numbers that give a meaningful contribution. For example, digit 013 has the 2  significant digits and zero is not a significant digit because digits 1 and 3 give meaningful contribution but digit zero does not value meaningful contribution. Similarly, the 89015 has a total of 5 significant digits and these digits are the 8, 9, 0, 1,  and 5.

What is the boiling point of water when 175.0 g of Na2SO4, a strong electrolyte is dissolved in 1.000 Kg of water?
liubo4ka [24]

Answer: 101.9^0C

Explanation:

Elevation in boiling point is given by:

\Delta T_b=i\times K_b\times m

\Delta T_b=T_b-T_b^0=(T_b-100)^0C = Elevation in boiling point

i= vant hoff factor = 3 (number of ions an electrolyte produce on complete dissociation)

Na_2SO_4\rightarrow 2Na^++SO_4^{2-}

K_f = freezing point constant = 0.512^0C/m

m= molality

\Delta T_b=i\times K_b\times \frac{\text{mass of solute}}{\text{molar mass of solute}\times \text{weight of solvent in kg}}

Weight of solvent (water)= 1.000 kg

Molar mass of solute Na_2SO_4 = 142 g/mol

Mass of solute Na_2SO_4  = 175.0 g

(T_b-100)^0C=3\times 0.512\times \frac{175.0g}{142g/mol\times 1.000kg}

T_b=101.9^0C

Thus the boiling point of water when 175.0 g of Na_2SO_4, a strong electrolyte is dissolved in 1.000 Kg of water is 101.9^0C

A solution is made by dissolving 10.7 g of magnesium sulfate, MgSO4, in enough water to make exactly 100 mL of solution. Calcula
adell [148]

Answer:

[MgSO₄] = 890 mM/L

Explanation:

In order to determine molarity we need to determine the moles of solute that are in 1L of solution.

Solute: MgSO₄ (10.7 g)

Solvent: water

Solution: 100 mL as volume. (100 mL . 1L / 1000mL) = 0.1L

We convert the solute's mass  to moles → 10.7 g / 120.36 g/mol = 0.089 moles

Molarity (mol/L) → 0.089 mol/0.1L = 0.89 M

In order to calculate M to mM/L, we make this conversion:

0.89 mol . 1000 mmoles/ 1 mol = 890 mmoles
