No. The number of a protons is not equal to it's atomic weight, instead it is equal to the 'atomic number'
Answer:
you gotta rotate it 90 degrees and get that screen fixed
Explanation:
Answer:either satellite tracking or probware.
Explanation:probate. Think its satalite tracking hope this helps.
The concentration of the solution is 8 M
<u><em>calculation</em></u>
<em> </em>Concentrati<em>on = moles/volume in liters</em>
<em> </em><em>step 1: find moles of HF</em>
<em>moles of HF =mass/molar mass</em>
<em>molar mass of HF = 1+ 19 )= 20 g/mol</em>
<em> moles is therefore = 32.0 g/ 20 g/mol= 1.6 moles</em>
<em>Step 2: convert ml to L</em>
<em>volume in liters = 2.0 x 10^2 / 1000 =0.2 l</em>
<em>step 3: find the concentration</em>
<em>concentration = 1.6 mol / 0.2 l = </em><em>8 M</em>
Answer:
total weight to expect = 331.60 grams
Explanation:
The flask wanted to be charged with 1.6 grams of sugar. The empty flask was weighed on a balance and it was determined to weigh 330 grams . The weight we would expect when we add the sugar can be computed as follows:
weight of the empty flask = 330 grams
weight of the sugar = 1.6 grams
The weight of the flask after adding the sugar will be the sum of the weight of the sugar and the empty falsk
Therefore,
Total weight to expect = 330 grams + 1.6 grams
total weight to expect = 331.60 grams
