Answer:
if 1 ant has 6 legs, then multiply. 6x8 is 48
Step-by-step explanation:
<span>299.2
The atomic weight of the new element is simply the weighted average of the isotopes. So
0.4030 * 296.78 + 0.5970 * 300.88
= 119.60234 + 179.62536
= 299.2277
Now the number of significant digits is the same as the number of significant digits of the LEAST PRECISE DATUM. And that would be the percentages at 4 significant digits each. So the result needs to be rounded to 4 significant digits which is 299.2</span>
- 4(20+22)
- 4(40+2)
This expression are equivalent to 4(42)
