3. Poking a metal rod into an electrical socket.
4. Touching the water in which an immersions heater is kept.
i think helium hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh
Here, Molar mass of N2O4 = 92.02 g/mol
So, Number of molecules in 1 mole (92.02 g) = 6.023 * 10²³
Number of molecules in 76.3 g = 6.023 * 10²³ / 92.02 * 76.3
= 6.023 * 10²³ / 1.20
= 5 * 10²³
In short, Your Answer would be approx. 5 * 10²³ molecules
Hope this helps!
Answer:
317.7778 g
Explanation:
Given data:
Flour required for 18 cup cakes = 260 g
Flour required for 22 cup cakes = ?
Solution:
We will calculate the flour required for 1 cup cake.
260 g /18 = 14.4444 g
Fluor required for 22 cupcakes,
22× 14.4444 g = 317.7778 g
In short,
22 cupcake/18 cup cake×260 g = 317.7778 g
Physical change because ther is force which is the electric current
