A student investigated the effect of light intensity on the rate of photosynthesis in the aquatic plant Cabomba caroliniana. They set the light source to different intensities and measured the volume of oxygen gas produced over a 10-minute period. Their results are shown in Table 1.
| Light Intensity (klxk\text{lx}klx) | Volume of oxygen gas (mm3mm^3mm3) produced in 10 minutes | |||
|---|---|---|---|---|
| Test 1 | Test 2 | Test 3 | Mean | |
| 1.5 | 22 | 25 | 22 | 23 |
| 3.0 | 64 | 59 | 63 | [Y] |
| 4.5 | 95 | 92 | 98 | 95 |
Calculate the mean volume of oxygen gas produced per 10 minutes (value [Y]) when the light intensity was 3.0 klxk\text{lx}klx.
