Answer:
48g of Magnesium.
Explanation:
We know that:
Mole=given mass/molar mass
Then, moles of aluminum = 54/27 = 2.
A/c to question ,
For 2 moles of magnesium it's mass is 2×24=48g.
Hence, the required mass for same number of magnesium atoms is 48g.
(Hope this helps can I pls have brainlist (crown)☺️)
Answer:
90.37 g
Explanation:
From Avogadro Number,
1 mole of every substance contains a particle number of 6.02×10²³
From the question,
1 mole of CH₄ contains 6.02×10²³ molecules.
But,
1 mole of CH₄ has a mass of 16 g
Therefore,
16 g of CH₄ contains 6.02×10²³ molecules
Then,
Y g will contain 3.4×10²⁴ molecules
Solve for Y
Y = (16× 3.4×10²⁴)/(6.02×10²³)
Y = 90.37 g
Answer:
The options are
A. a hypothesis
B. a theory
C. a research question
D. a scientific explanation
The answer is A. a hypothesis
Explanation:
A hypothesis is referred to as a brief explanation on the occurrence of an event.
In the example above using of warm water on plants was inferred to make it grow faster as hot water increases the metabolism.
