Significant Figures For 7.06 × 10^5 ÷ 5.3 × 10^-2

Kay [80]

Answer:

$\boxed{\text{two}}$

Explanation:

In multiplication and division problems, your answer can have no more significant figures than the number with the fewest significant figures.

$\dfrac{7.06 \times 10^{5}}{5.3 \times 10^{-2}}= 1.332 075 472 \times 10^{7}$ (by my calculator)

There are three significant figures in 7.06 and two in 2.3.

You must round to $\boxed{\textbf{two}}$ significant figures and report the answer as 1.3 × 1.0⁷.

In lipid bilayers, there is an order-to-disorder transition similar to the melting of a crystal. Comparing a lipid bilayer that

prisoha [69]

Answer:

The lipid bilayer made up of Palmitic acid will have a higher melting transition temperature

Explanation:

The one with a higher melting transition temperature is the lipid layer with a higher melting temperature

Melting temperature of palmitoleic acid = -0.5°C

Melting temperature of palmitic acid = 62.9°C

Hence the lipid bilayer made up of Palmitic acid will have a higher melting transition temperature

What volume (mL) of the sweetened tea described in Example 1 contains the same amount of sugar (mol) as 10 mL of the soft drink

S_A_V [24]

The question is incomplete, the complete question is:

What volume (mL) of the sweetened tea described in Example 3.14 contains the same amount of sugar (mol) as 10 mL of the soft drink in this example. The example is attached below.

Answer: 75 mL of sweetened tea will contain the same amount of sugar as in 10 mL of soft drink

Explanation:

We first calculate the number of moles of soft drink in a volume of 10 mL

The formula used to calculate molarity:

$\text{Molarity of solution}=\frac{\text{Moles of solute}\times 1000}{\text{Volume of solution (mL)}}$ .....(1)

Taking the concentration of soft drink from the example be = 0.375 M

Volume of solution = 10 mL

Putting values in equation 1, we get:

$0.375=\frac{\text{Moles of sugar in soft drink}\times 1000}{10}\\\\\text{Moles of sugar in soft drink}=\frac{0.375\times 10}{1000}=0.00375mol$

Calculating volume of sweetened tea:

Moles of sugar = 0.00375 mol

Molarity of sweetened tea = 0.05 M

Putting values in equation 1, we get:

$0.05=\frac{0.00375\times 1000}{\text{Volume of sweetened tea}}\\\\\text{Volume of sweetened tea}=\frac{0.00375\times 1000}{0.05}=75mL$

Hence, 75 mL of sweetened tea will contain the same amount of sugar as in 10 mL of soft drink
