Answer:
163 kilograms per cubic feet.
Explanation:
To solve this problem, first we <u>convert 5.77 g/cm³ to kg/cm³</u>:
- 5.77 g/cm³ *
= 5.77x10⁻³ kg/cm³
Then we <u>convert kg/cm³ to kg/ft³</u>, by <em>converting cm³ to ft³</em>:
- 5.77x10⁻³ kg/cm³ *
= 163 kg/ft³
So the density is 163 kilograms per cubic feet.
the mass of potassium iodide is 0.360 g
calculation
step 1: write the balanced molecular equation
Pb(NO3)2 (aq) + 2 Ki (s)→ Pbi2(s) + 2KNO3
step 2 ; calculate the moles of Pbi2
moles = mass /molar mass
= 0.500 g / 461 .0 g/mol =0.0011 moles
step 3: use the mole ratio to calculate the moles of Ki
Ki: Pbi2 is 2:1 therefore the moles of ki = 0.0011 x 2/1 = 0.0022 moles
step 4 : find the mass of Ki
mass= moles x molar mass
=0.0022 moles x 166g/mol =0.365 g which is approximate 0.360 g
The answer is B
Vaporization

im sorry dude, just trying to complete my daily challenge
Explanation:
Answer:
The answer to your question is below
Explanation:
A qualitative property of matter is a property characteristic of a substance like color and flavor.
A quantitative property of matter is a property when we get a number.
A) it's a circular shape is a qualitative property because the shape is a qualitative property and shape is not represented by a number.
B) its mass is 1.5 kg is a quantitative property because we know a number of this mass.
C) it tastes like chocolate is a qualitative property because the flavor is characteristic of a substance and flavor is not measured in numbers.
D) it is 30 cm in diameter it is a quantitative property, we know the exact dimension of it.
E) its icing is melting is a qualitative property, melting is a property of ice, it just happens.
