Salt crystals are shaped like cubes. Salt is part of the _____. isometric crystal system monoclinic crystal system hexagonal cry

Answer:

Mass and weight are very similar, but different.

Explanation:

Mass is how much matter an object contains. Weight is how much force gravity is putting on an object.

Answer:

278 atm

Explanation:

We're gonna use this formula:

P₁ = 177 atm

T₁ = 298 (Convert Celsius to kelvins by adding 273)

P₂ = ?

T₂ = 468 (195 + 273)

We got

We can cross-multiply or multiply both sides by 468

I'm gonna go with the latter

Answer:

The coffee is the solvent. The sugar is the solute. The sweetened coffee is the solution.

Explanation:

A. The molar mass of gold is 196.97 g/mol. To find the number of moles, we divide the mass by the molar mass:
(45.65 g Au) / (196.97 g/mol) = 0.2318 mol Au (rounded to 4 significant figures)

B. One mole contains 6.02 x 10^23 atoms, so we multiply this to the number of moles from part A to find the total number of atoms:
(0.2318 mol Au) * (6.02 x 10^23 atoms/mol) = 1.395 x 10^23 Au atoms

Answer:

Molarity of Unknown Acid = 0.1332 M

Explanation:

Data for solving problem:

Molarity of base in buret (M₁)= 0.1517 M

volume of the acid in Erlenmeyer flask (V₂)= 25.0 mL

Volume of the base in the buret (V₁) = final volume of buret - initial volume in buret

final volume of buret = 22.5 mL

initial volume in buret = 0.55 mL

So

Volume of the base in the buret (V₁) = 22.5 mL -0.55 mL = 21.95 mL

Volume of the base in the buret (V₁)  = 21.95 mL

Molarity of Unknown acid in the Erlenmeyer flask (M₂) = To be find

Explanation:

It is acid base titration and  formula for this titration is as follows:

Molarity of base x Volume of base = Molarity of acid x volume of acid

it can be written as

M₁V₁ = M₂V₂ -------------------- equation (1)

we have to find M₂

so by rearrangment the equation (1)

M₁V₁ / V₂ = M₂ ------------------ equation (2)

put the values in equation in equation (2)

M₂ = 0.1517 M x 21.95 mL / 25.0 mL

M₂ = 3.3298 /25.0

M₂ = 0.1332 M

so the Molarity of Unknown acid is <u>0.1332 M</u>
