Answer: last option, 0.22 N


Explanation:


<em>Weight</em> is the attractive force that the Earth exerts on the objects, and it is calculated as the product of the mass of the object and the gravitational acceleration: w = mg.


Gravitational acceleration depends of the height of the objects but it is almost a constant at the normal altitudes (near the surface) with which this kind of problems deal with. Of course, this is true at <em>sea level on Earth.</em>


A standard value used for g is 9.81 m/s^2. And for quick or approximate calculations it can be used 10 m/s^2.


So, to calculate what is the<em> weight of a mouse at sea level on Earth</em>, when you have that the mass of a mouse is around 22 grams (0.022kg), you  folow these steps:


1) Data:

  • m = 0.022 kg
  • g = 10 m/s^2
  • w = ?

2) Formula: w = mg


3) Solution: w = 0.022 kg (10 m/s^2) = 0.22 N.


So, the answer is the last option: 0.22N.

HACTEHA [7]

Answer:

Ba(OH)2 + H2SO4 ------> BaSO4 + 2H2O

1) Moles of Ba(OH)2 = moles of H2SO4 = 0.025L x 2)0.02M = 5.0 x 10^-4M

Concn of Ba(OH)2 in g/L = 5.0 x 10^-4M x 171.33g/mol = 0.086g/mol

Suppose that a fictitious element, x, has two isotopes: 59x (59.015 amu) and 62x (62.011 amu). the lighter isotope has an abunda
professor190 [17]

The atomic mass of the element would simply be equal to the sum of the weighted average of each isotope, that is:

atomic mass = 59.015 amu * 0.717 + 62.011 amu * (1 – 0.717)

<span>atomic mass = 59.863 amu</span>
