Sedimentary rocks are classified on the basis of the texture (grain size) of the rock, and composition.

You go out to dinner and the bill comes to $ 26.37. How much should you tip if you want the tip to be 19.0 % of the bill?

Lerok [7]

If we want to tip 19% or 0.19 of a bill of $26.37

We just multiply 26.37*0.19=$5.01

Any questions please feel free to ask. Thanks

What is the vapor pressure of a 45.0 % solution of glucose, c6h12o6, at 90.0°c, given that the vapor pressure of pure water at t

Vadim26 [7]

Weight of solute = 45 g and weight of solvent = 55 g
M.wt of solute = 180 P⁰ = 526 mmHg
number of moles of solute = 45 / 180 = 0.25 mol
number of moles of solvent = 55 / 18 = 3.05 mol
According to Rault's law:
$\frac{P^{0} - P^{s} }{P^{0} } = \frac{n_{solute} }{n_{solute} + n_{solvent}}$ = 0.25 / (0.25 + 3.05)

$\frac{526 - P^{s} }{526} = 0.076$

$P^{s} = 486.15 mmHg$

Answer:

615 g

Explanation:

In order to convert from moles of any given substance into grams, we have to use said substance's molar mass, as follows:

# moles * Molar mass = grams of substance.

Thus, we now calculate the molar mass of beryllium iodide, BeI₂, using the molar masses of the elements:

Molar Mass of BeI₂ = Molar Mass of Be + (Molar Mass of I)*2 = 262.821 g/mol

Finally we calculate how many grams are there in 2.34 moles of BeI₂:

2.34 mol * 262.821 g/mol = 615 g
