Explanation:
Molecular mass of NO2= 14+16×2=46
1 mole NO2 = 46 gm of NO2
9.4 moles of NO2= 46×9.4 gm= 432.4 gm NO2.
I think the best answer is D. Minor parties do not always get a support from foreign officials in order for them to get elected. They also have difficulties because they are a small political party. They do not have enough resources or supporters as compared to larger political parties.
Volume of water displaced is equal to the volume of the metal. So 41 - 20 = 21 ml. Density = mass / volume so density = 159 / 21 = 7.57 g/ml
<u>Answer:</u> The density of NaCl solution is 3.930 g/mL
<u>Explanation:</u>
We are given:
Mass of cylinder,
= 21.577 g
Mass of NaCl and cylinder combined, M = 39.664 g
Mass of NaCl,
= 
To calculate density of a substance, we use the equation:

We are given:
Mass of NaCl = 18.087 g
Volume of NaCl solution = 4.602 mL
Putting values in above equation, we get:

Hence, the density of NaCl solution is 3.930 g/mL
Answer:
The correct option is (d).
Explanation:
It is given that,
1$ = 1500 pesos
We need to convert 360 pesos into dimes
We can convert 360 pesos to dollars as follows:

360 pesos is equal to $0.24
Also, 1 dollar = 10 dimes
We can covert 0.24 dollar to dimes as follows :
0.24 dollar = 10 × 0.24 dimes
0.24 dollar = 2.4 dimes
or
360 pesos = 2.4 dimes
