How would you calculate the atomic mass of an atom of silver (Ag)?
iren [92.7K]

Answer:

107.8682 u

Explanation:

Well Silver has an atomic mass of aproximately 107.9. 1 mole of silver atoms = 107.9g and there are 6.02x10^23 atoms in one mole. Therefore to find mass of one atom you should divide the mass by Avodgadro's constant to find the mass of one atom because they all have an even distribution of mass.

The average atomic mass of the element takes the variations of the number of neutrons into account, and tells you the average mass per atom in a typical sample of that element. For example, the element silver (Ag) has two naturally occurring isotopes: Ag-107 and Ag-109 (or 107Ag and 109Ag).

How would you test a colorless crystalline compound to determine if it was a hydrate?
Cloud [144]

A hydrate is a substance where in it contains water and other constituent elements. To know whether if that compound was a hydrate,you should record its mass, then put it in a test tube and heat it with a Bunsen burner. If the compound is a hydrate, the water in the compound will discharge in the form of water vapor. At the next 5-10 minutes, remove it in the test tube and weigh it up again. If the mass is now fewer, that means that there was water existing that has now evaporated, and the compound was a hydrate.

a scientist is measuring the measuring the temperature change in a chemical compound. the temperature dropped 11 per hr from the
stepladder [879]

Answer:

\large \boxed{134 \, ^{\circ}\text{C}}

Explanation:

1. Calculate the temperature drop

\text{Temperature drop} = \text{4 h} \times \dfrac{11 \,^{\circ}\text{C}}{\text{1 h}} = 44 \,^{\circ}\text{C}

2. Calculate the original temperature

\begin{array}{rcl}\text{Final Temperature} & = & \text{original temperature - temperature drop}\\90 ^{\circ}\text{C} & = & \text{original temperature - 44} \, ^{\circ}\text{C}\\\text{Original temperature}& = & \mathbf{134 \, ^{\circ}}\textbf{C}\\\end{array}\\\text{The original temperature was $\large \boxed{\mathbf{134 \, ^{\circ}}\textbf{C}}$}
